Q. Assertion : An increase in surface area increases the rate of evaporation.
Reason : Stronger the inter‐molecular attractive forces, fast is the rate of evaporation at a given temperature.

AIIMSAIIMS 2002Surface Chemistry

Solution:

More is the surface area, fast is the rate of evaporation at a given temperature this is due to the fact that more surface area means more number of molecules at the surface which can then be evaporated easily. Strong intermolecular forces of attraction slows down the rate of evaporation.
