Vedclass · Answer

(A) The given process represents the phase transition of water from liquid to gas at its boiling point $(373.15 \ K)$ and standard pressure $(1 \ bar)$.Since the system is in equilibrium at the boiling point, the change in Gibbs free energy is $\Delta G = 0$.During the phase change from liquid to gas, the disorder of the system increases, which means the entropy change is positive, $\Delta S > 0$ (or $\Delta S = +ve$).

For the following process $H_2O_{(l)} (1 \ bar, 373.15 \ K) \rightleftharpoons H_2O_{(g)} (1 \ bar, 373.15 \ K)$, identify the correct set of thermodynamic parameters.
