Clausius-Clapeyron equation:
Clausius-Clapeyron equation is a relationship between the enthalpy of evaporation, saturation pressure and temperature, and the specific volume of the two phases involved.
This equation can be derived from Maxwell equation:
P is the pressure, T is the temperature, v is the specific volume and s is the specific entropy
During a phase change, the pressure and temperature are dependent properties
During phase change
This equation is useful to find out the latent heat (enthalpy change hfg) at the change of phase for a given pressure.
Therefore statement II) is incorrect as it has represented the Clausius-Clapeyron equation in the wrong way.
