Question

How does the kinetic molecular theory help us understand the temperature dependence of chemical reactions?

Answer 1

Answer:

The chemical reactions are depends up on the temperature. Temperature is a measure of motion of the particles, which increases by supplying thermal heat energy.  According to the Kinetic molecular theory, if the reaction happens between two compounds, they collide with enough energy to overcome the activation of energy barrier.  

The kinetic energy of the particles increases with increase in temperature. This results in collision being more energetic and therefore more likely to be able to overcome the activation barrier. The rate of chemical reactions increases with more collision of molecules.

So, the temperature is the important parameter to increase the rate of reactions.
