What else can I help you with?
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
What happens to the potential energy of the molecules in a reaction?
The potential energy of the molecules change during a reaction.
What is the significance of the standard Gibbs free energy change (G') in determining the feasibility of a chemical reaction?
The standard Gibbs free energy change (G') is important in determining if a chemical reaction is feasible because it indicates whether the reaction will occur spontaneously. If G' is negative, the reaction is likely to proceed forward without added energy. If G' is positive, the reaction is unlikely to occur without external energy input.
With Reference to molecular collision theory explain what activation energy is?
Collision theory states that when suitable particles of the reactant hit each other, only a certain amount of collisions result in a perceptible or notable change; these successful changes are called successful collisions. The successful collisions must have enough energy, also known as activation energy, at the moment of impact to break the pre-existing bonds and form all new bonds. This results in the products of the reaction. Increasing the concentration of the reactant brings about more collisions and hence more successful collisions. Increasing the temperature increases the average kinetic energy of the molecules in a solution, increasing the amount of collisions that have enough energy. Collision theory was proposed independently by Max Trautz in 1916 and William Lewis in 1918.
Is activation energy added or just there?
Activation energy is the amount of energy that should be gained by potential reactants, for a reaction to occur. A reaction can be occurred by reducing the activation energy of the reaction or increasing the activation energy of the reactants. Activation energy should be added.
What can a reaction occurs to added to break bonds?
Any chemical reaction need an activation energy.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
What must be added to a reactant to start a chemical reaction?
Either an energy source to start the reaction or a catalyst.
What is the term for the amount of energy that needs to be added for chemical reactions to start?
activation energy
What will change when a catalyst is added to a chemical reaction?
When a catalyst is added to a chemical reaction, the rate of the reaction will increase without being consumed in the process. This means that the reaction will reach equilibrium faster and require less activation energy. The overall chemical equilibrium and products formed will remain the same.
What is energy of activation?
The energy of activation is the minimum amount of energy required to start a chemical reaction. It acts as a barrier that reactants must overcome to transform into products. This energy is necessary to break existing bonds and initiate the formation of new ones during a reaction.
Is heat energy added a liquid causes it to evaporate is it a chemical reaction?
No. It's just a change of state.
What causes chemical bond to break during a reaction?
Energy is added to break bonds, so there is your simple answer. But some bonus info for you:Bond energy is the amount of energy it will take to break a bond (ironic, because it sounds like the amount of energy it will take to MAKE a bond, even though it's the opposite).Energy is released when bonds form, and the same amount of energy is released when the bond is broken.
What will most likely happened if an appropriate enzyme is added to a chemical reaction?
The enzyme will act as a catalyst, a compound that lowers that activation energy of the reaction, and therefore, increase the rate of the reaction.
Which component is affected when a catalyst is added to a chemical reaction?
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
