Solution

The correct option is C Statement 1 is correct but Statement 2 is not correct.
Answer( C)

To increase the rate of a reaction you need to increase the number of successful collisions. One possible way of doing this is to provide an alternative way for the reaction to happen which has a lower activation energy.so catalysts are added to reaction mixture. so statement 1 is true and statement 2 is false.
