(a)
Interpretation:
If the Clausius-Clapeyron equation is strictly applicable to the given phase transitions is to be predicted.
Concept introduction:
The clausius-clapeyron equation states the relation between vapor pressure and the absolute temperature. It is derived by using some assumptions like the ideal gas behaviour and the change in volume of phases is equal to the volume of gas phase.
Some another assumptions include non-varying enthalpy and entropy of transition values. At high pressure, near the critical point and over range of large temperature, these assumptions get failed.
