    Consider the following liquid - vapour equilibrium. \[\text{Liquid }\text{Vapour}\] Which of the following relations is correct?

    A) \[\frac{d\ell nG}{d{{T}^{2}}}=\frac{\Delta {{ }_{v}}}{R{{T}^{2}}}\]      

    B)  \[\frac{d\ell nP}{dT}=\frac{-\Delta {{ }_{v}}}{RT}\]

    C)   \[\frac{d\ell nP}{d{{T}^{2}}}=\frac{-\Delta {{ }_{v}}}{{{T}^{2}}}\]      

    D)   \[\frac{d\ell nP}{dT}=\frac{\Delta {{ }_{v}}}{R{{T}^{2}}}\]

    Correct Answer: D

    Solution :

    Clausius - Clapeyron's equation\[\frac{d\,\ln P}{dT}=\frac{\Delta {{H}_{v}}}{R{{T}^{2}}}\]
