If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
A catalyst is more effective in finely divided form because finely divided form has more surface area. Therefore there is an increase in active centres on the surface3.
