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 as

$\mathrm{P}=\mathrm{A} {\mathrm{e}}^{-\frac{∆{\mathrm{H}}_{\mathrm{v}}}{\mathrm{RT}}}$

P=VP of liquid , A=pre exponential factor

$∆{\mathrm{H}}_{\mathrm{v}}$= Enthalpy of vapourisation ( it is always positive)

R = universal gas constant  ,    T = Absolute temperature
