72. The expression, $$\Delta {\text{G}} = {\text{nRT}}.l{\text{n}}\frac{{{{\text{P}}_2}}}{{{{\text{P}}_1}}},$$ gives the free energy change
74. Entropy change of the reaction, H2O(liquid) ⇒ H2O(gas), is termed as the enthalpy of
75. Specific __________ does not change during a phase change (e.g. sublimation, melting, vaporisation etc.).
