Question

VAPOUR PRESSURE OF A LIQUID IN A CLOSED CONTAINER DOES NOT DEPEND UPON: ?

Answer 1

Answer:

Vapour pressure of a liquid in a closed container does not depend upon the amount of the liquid or shape/size of the vessel.

Explanation:

Consider the equilibrium,

Liquid = Gas

Here, at equilibrium,  

Kp = Pgas

Pgas is vapor pressure of liquid (the pressure exerted by vapors on the surface of liquid at equilibrium).

We know well that Kp changes only with temperature and is independent of the concentration or amount of substance.

The vapour pressure of a given liquid is constant at a given temperature.

It does not depend upon the amount of the liquid or shape/size of the vessel.

The vapour pressure of a liquid increases with increase in temperature (evaporation being endothermic process).

Answer 2
