What can increase the chance of a reaction when two molecules collide?
An increase in the temperature usually increases the rate of reaction by increasing the number of collisions.
Why does increasing the pressure or concentration increase the rate of reaction?
Keep in mind that the reaction can only occur if the particles collide with enough power in the right position.The rate of reaction generally depends on four factors:ConcentrationNature of reactantsTemperatureCatalystsFor gases, pressure is also a factor. Say we have 1L of a gas and we compress it to 0.5L. Decreasing the volume will increase the pressure, and with a lower volume with the same number of particles increases the molarity (M). And as a convention, increasing the molarity/concentration increases the rate of the reaction because there is more of a chance for particles to collide in a small space rather than in a large space.Temperature also increases the rate of the reaction because it increases the kinetic energy of the particles, which will mean that more particles have the energy equal to or above the activation energy for the reaction to occur.
Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
What increases the chance of reaction when two molecules collide?
increasing the concentration in the molecue
What are 4 things that can affect the rate of a reaction?
1. Temperature: Depending on the temperature of the reactants, the reaction rate will differ. The higher the temperature (or the hotter the reactant is), the quicker the reaction will occur. The cooler the reactant is, the longer it will take for a reaction to take place. The heat causes the particles to move quickly, and due to the Collision Theory, which states that in order for a reaction to occur, molecules must collide, the particles will be more likely to bump into each other, and so the reaction will occur faster.2. Concentration: The higher the concentration of a reactant, the quicker the reaction will occur. This means that there are more particles of that particular substance, meaning it will collide more frequently into the particles of the other reactant. This increases the reactant rate because the more concentrated a reactant is, it means that the less space there is between the two reactants.3. Surface Area: Basically, the more particles that are exposed during the experiment, the faster the reaction will occur. The more the particles are exposed, the faster it is for the other reactant to collide into the particles, meaning the reaction rate will increase.4. Catalysts: Catalysts are substances that increase the rate of reaction by speeding up the reaction without being used up in the reaction. It does not affect the reactants in any other way than making them collide into each other more frequently, and it doesn't affect the product (or products) produced
How does average particle speed affect the reaction rate?
As the speed of the particles increase, it causes them to collide with the other particles in which they are reacting with more frequently, increasing the reaction rate.
According to kinetic and collision theory why does increasing the temperature of the reaction increase the rate of reaction?
The likelihood that two particles will collide in a given time increases. The number of particles per volume increases.
What can increase the chance of a reaction when two molecules collide?
An increase in the temperature usually increases the rate of reaction by increasing the number of collisions.
What happens to the reaction rate when reactants particles collide more often?
In brief, the reaction rate increases. When there are more collisions, the more probability to collide them in the proper direction. The overall reaction will come to the equilibrium in a lesser time.

average kinetic energy, enough energy, reaction rate
If the temperature of a chemical reaction is increased the reaction rate?
It depends if the reaction is endothermic (requires heat/energy) or is exothermic (requires no heat/energy and produces heat/energy). In general, most reactions are endothermic and require some amount of energy to 'go' and hence, an increase in temperature will increase the rate of reaction. However, in exothermic reactions, introducing heat can halt the reaction as well as reverse it, if said reaction is reversible.

The reason for using powered calcium carbonate CaCO3 and heating the reaction mixtures up are?
Powdered: increases surface area the reaction happens over, thereby increasing the rate of reaction Heat: Provides energy for the reaction. Particles move faster, therefore collide more frequently. also, more particles have sufficient energy to react when they collide. This also increases rate.
Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
What is the connection between temperature collisions and reaction rate?
More collisions between particles of matter means a faster reaction rate. When you increase the kinetic energy of a sample of matter, you increase the number of particle collisions, as well as the force with which they collide. This in turn increase the rate of reaction.
Could decreasing the surface area increase the rate of a reaction?
Not really... it surely would slow it down as there is less surface area for particles to collide with.
