Question

When we increase the temperature, the rate of reaction increases because of:

• A. more number of collisions
• B. decrease in mean free path
• C. more number of energetic electrons
• D. less number of energetic electrons

Answer 1

The correct option is A more number of collisions

Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions.

It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

Hence, option A is correct.
