Question

According to collision theory of reaction rates:

• A. every collision between reactant molecules leads to a chemical reaction
• B. rate of reaction is proportional to the velocity of the molecules
• C. rate of reaction is proportional to the average energy of the molecules
• D. rate of reaction is proportional to the number of collisions per second

Answer 1

The correct option is D rate of reaction is proportional to the number of collisions per second

According to collision theory rate of reaction is proportional to the number of collisions per second. And all the collision will not result in formation of product. Only those collision where molecules have enough activation energy and proper orientation will lead to a chemical reaction.
