Question

Some liquid is taken in an evacuated vessel and the vessel is sealed. Which of the following graph will correctly represent the achievement of equilibrium of liquid with its vapour at constant temperature? (r_e = rate of evaporation, r_c = rate of condensation)

Prashant Kotian · Accepted Answer

Correct answer: B. evaporation rate r_e is constant at constant temperature. condensation rate r_c starts at 0 and increases with vapor density. equilibrium is reached when r_c increases to equal r_e.
