Why does increase in temperature increase the rate of a reaction?

To answer it, you have to imagine small particles in a solution.
Let's take a simple reaction like A + B -> C
To react, A and B have to bump each others.
If you heat the solution, atoms will move faster, so you will increase the probability of having shocks between A and B, then you will speed the reaction.
It's simplified, but it almost explains what really happens.

∙ 16y agoBy definition, an exothermic reaction is a reaction which produces heat. In other words, one of the products of the reaction is heat. Burning wood or coal is an exothermic reaction for instance. Because heat is released by the reaction, the temperature of the surroundings goes up as the surrounding absorb that heat.

What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
How does temperature affects the rate of industrial reaction?
It depends. A higher temperature will speed up an endothermic reaction, but slow down an exothermic reaction.
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
How is the rate of reaction affected when the temperature increases?
As the temperature increases, the reaction time decreases.
What does temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
Is temperature essential in determining the reaction rate?
yes, as the reaction rate increases with increase in the temperature
How do changes in temperature affect the rate of a reaction?
An increase of temperature increase the rate of a reaction.
How does heat affect the rate of the reaction?
Increasing the temperature the reaction rate increase.
What leads to an increase in the rate of a chemical reaction?
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
In general an increase in temperature?
A general increase in temperature increases the reaction rate.
What happens to the rate constant of a chemical reaction when the temperature increases?
Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
Increasing the temperature increases the rate of a reaction by?
An increase in temperature is an increase in kinetic energy. This causes there to be an increase in the collision frequency as well, so the rate of reaction goes up.
Increased temperature usually leads to an increase in reaction rate because collisions are?
The increase in reaction rate is due to an increase in the number of collisions. This is because an increase of temperature causes an increase in molecular motion.
Which of the following tends to increase the rate of a chemical reaction?
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
