Question

According to collision theory of chemical reactions rates of the reaction increase with increase in the temperature of a reaction because of

• A. increase in the velocity of the reacting molecules
• B. increase in the number of collisions
• C. increase in the number of molecules having the activation energy (threshold energy)
• D. None of the above

Answer 1

Answer: (C)

Increase in the number of molecules having the activation energy (threshold energy) increases the rate of reaction.
