The graph obtained by taking vapour pressure (P) of a liquid on y-axis and temperature (T) on x-axis will be

V.P of liquid increases exponentially with temperature.variation of V.P of liquid with temperature is mathematically given asP=VP of liquid           ,         A=pre exponential factor = Enthalpy of vapourisation ( it is always positive)R = universal gas constant  ,    T = Absolute temperature(3) is correct
