To obtain the integrated form of the Clausius-Clapeyron equation \(\ln \frac{P_{2}}{P_{1}}=\) \(\frac{\Delta H_{V}}{R}\left(\frac{1}{T_{1}}-\frac{1}{T_{2}}\right)\) from the exact Clapyeron equation, it is assumed that the

(a) Volume of the liquid phase is negligible compared to that of the vapour phase

(b) Vapour phase behaves as an ideal gas

(c) Heat of vaporization is independent of the temperature

(d) All of these.
