Rate of evaporisation increases with increase in 3 surface area, but not vapour pressure. Why?

Text Solution

Verified by Experts

As the surface area increases, more number of molecules will escape per unit time. Therefore, rate of evaporation increases. But vapour pressure in nothing but pressure and is defined as force per unit area.
