Heating up a reaction does which of the following:
Group of answer choices

A. Increases the number of collisions as well as the strength of the collision

B. Increases the strength of the collisions only.

C. Increases the number of collisions only.

D. No effect is found on the reaction by increasing the temperature.

According to the collision theory, the reaction take place when the collision occur and molecules having sufficient energy or threshold energy for collision.

The collision of molecules depend on the kinetic energy of molecules. Greater the kinetic energy greater the number of molecules collide. Lesser the kinetic energy lesser will be collision.

How temperature affect the collision theory ?

With an increase in temperature, there is an increase in energy that can be converted into activation energy in a collision, and that will increase the reaction rate. A decrease in temperature would have the opposite effect. With an increase in temperature, there is an increase in the number of collision.

Thus from the above conclusion we can say that Heating up a reaction does increase the number of collision only.

Hence, Option C is correct answer.
