Question

The vapor pressure of liquid is the pressure exerted by its vapor when the liquid and states are in equilibrium. The relationship between vapor pressure P and temperature T is expressed by the Clausius-Clapeyron equation where P_1 and P_2 are the vapor pressures e absolute temperatures T_1 and T_2 respectively, Delta H_vap, is the heat of vaporization of the substance in joules per mole, and R is the ideal gas constant, which is equal to 8.3145 J/(mol-K). The heat of vaporization of water is 4.07 times 10^4 J/(mol-K) Which the following factors affect the vapor pressure of a liquid? Check all that apply. surface area of the liquid temperature amount of liquid addition of solute atmosphere pressure type of quid

Explanation / Answer

Surface area of the liquid is more vapour pressure of liquid is more

As temparature increases vapour pressure of liquid also increases

Amount of liquid will not affect vapour pressure, because for a given amount of liquid vapour pressure is always a constant value

Addition of non-volatile solute decreases vapour pressure but addition of volatile solute increases vapour pressure

Atmospheric pressure doesn't affect vapour pressure

Vapour pressure depends on nature of liquid
