Does an equation indicates the number of atoms of each product and each reactant involved in a reaction?
Not quite. A properly balanced an equation indicates the number of atoms of any elemental product and any elementalreactant involved in a reaction, along with the number of molecules of any molecular compound product and any molecular compound reactant involved in the reaction. The original sentence is deficient because in any chemical reaction, there must be at least one non-elemental product or reactant.
How is energy related to the movement of molecules?
Energy is required for molecules to move. At higher temperatures, molecules have more kinetic energy, causing them to move faster and more freely. Conversely, at lower temperatures, molecules have less kinetic energy and move slower.
Which accounts for the increase in the rate of reaction when a catalyst is added to a reaction system. Does the entropy of the reaction increase?
When two molecules react with each other they must form a transition state. The higher the energy of the transition state the less likely it is for the two molecules to react with each other. Catalysts lower the energy of the transition state. This makes it more likely for molecules to react with one another, which speeds up the overall reaction. Entropy is unrelated. Reactions that break apart molecules increase entropy. Reactions that combine molecules together diminish entropy. Both types of reactions can be sped up by catalysts.
How is kinetic energy related to heat production?
Kinetic energy is directly related to heat production through the movement of molecules. When an object or substance gains kinetic energy, its molecules move faster, colliding with each other more frequently and with greater force, which generates heat. The heat produced is a form of energy resulting from the kinetic energy of the particles within the system.
Temperature is relative to the energy of the molecules?
Increasing temperature will increase molecular speed.An object with less massive molecules will have higher molecular speed at the same temperature.When kinetic temperature applies, two objects with the same average translational kinetic energy will have the same temperature. An important idea related to temperature is the fact that a collision between a molecule with high kinetic energy and one with low kinetic energy will transfer energy to the molecule of lower kinetic energy.
Difference between threshold energy and activation energy?
THRESHOLD ENERGY(T.E) You consider any particular reaction. the molecules of the reactants must necessarily possess certain minimum value of kinetic energy for the collision with other reactant and to from product . this minimum energy that the reactant molecules should possess is known as threshold energy (T.E) ACTIVATION ENERGY (A.E) Do you think all the molecules will possess this particular minimum kinetic energy required to form products? obviously not. if you take the graph of no of molecules vs their kinetic energy graph, you will see that only few molecules possess this minimum kinetic energy. so for other molecules also to participate in the reaction you need to provide certain extra energy to them by some means which is known as the activation energy. (A.E) Now the question arises ,how to calculate the activation energy. suppose in a reaction the average kinetic energy of the molecules of reactant be 10Joules , threshold energy is 50Joules. so what energy should be supplied for all the molecules to react. this is nothing but T.E - Average kinetic energy i.e.,50-10=40Joules. this is what is known as activation energy so ACTIVATION ENERGY (A.E) THRESHOLD ENERGY (T.E) AND AVERAGE KINETIC ENERGY (K.E) ARE RELATED AS A.E=T.E - K.E
What is the Relation between frequency factor and steric factor?
The frequency factor and steric factor are both parameters that affect the rate of a chemical reaction. The frequency factor is related to the number of collisions between reactant molecules per unit time, while the steric factor accounts for the influence of molecular geometry and orientation on the reaction rate. Together, they determine how often reactant molecules collide in the correct orientation and with sufficient energy to overcome the activation energy barrier for the reaction to occur.
What is the noun for reactive?
The noun form of the adjective reactive is reactiveness.The related nouns are reactant (The material that reacts), reactor (The apparatus which contains the reaction), and reaction (The process the reactant undergoes).
What is the energy related to the movement molecules?
The energy related to the movement of molecules is called kinetic energy. This energy is a result of the motion of particles and is dependent on their mass and velocity. Temperature is a measure of the average kinetic energy of molecules in a substance.
The measure of the average kinetic energy of a group of molecules?
The measure of the average kinetic energy of a group of molecules is expressed as temperature. As temperature increases, molecules move faster and their kinetic energy increases. This average kinetic energy is directly related to the temperature of the system.
Is kinetic energy higher in larger molecules?
Kinetic energy is directly related to the speed of molecules, not their size. In general, larger molecules tend to have higher potential energy due to their higher mass, which can result in higher kinetic energy when they are moving.
How are kinetics and reaction rate are related?
Increasing the concentration of the reactants will increase the frequency of collisions between the two reactants. So this is collision theory again. You also need to discuss kinetic theory in an experiment where you vary the concentration. Although you keep the temperature constant, kinetic theory is relevant. This is because the molecules in the reaction mixture have a range of energy levels. When collisions occur, they do not always result in a reaction. If the two colliding molecules have sufficient energy they will react.
How does the average kinetic energy of a gas relate to its temperture?
The average kinetic energy of a gas is directly proportional to its temperature. This is described by the kinetic theory of gases, which states that the average kinetic energy of gas molecules is directly related to the temperature of the gas. As temperature increases, the average kinetic energy of the gas molecules also increases.
The temperature of an object is related to the?
The temperature of an object is related to the average kinetic energy of its molecules. When molecules have higher kinetic energy, the temperature of the object is higher. Temperature is a measure of the internal energy of an object.
How are the words reactant product chemical reaction and catalyst related?
Reactants: the initial substances in a chemical reaction Products: the final substances in a chemical reaction Catalyst: a stimulator of a chemical reaction, not directly involved in the reaction, remain unchanged
What is thermal energy?
related to the motion of molecules
A measure of the speed of molecules is the?
A measure of the speed of molecules is the temperature of the substance they are in. Temperature is related to the average kinetic energy of the molecules, and the higher the temperature, the faster the molecules will be moving.
