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.
Options
- AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
- BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
- CIf the assertion is true but the reason is false.
- DIf both assertion and reason are false.
Correct answer
C. If the assertion is true but the reason is false.
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.
