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.

Step-by-step 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 inter-molecular forces of attraction slows down the rate of evaporation.
