Assertion :- An increase in surface area...

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.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
C
It is true that if we increase the surface area, the rate of evaporation also increase as evaporation is always takes place from the surface. But if the intermolecular attraction is stronger, than the rate of evaporation is slower.
