Question

For a certain decomposition
\[ X_2 Y_4 (g) \rightleftharpoons 2 XY_2 (g) \] Degree of dissociation of \( X_2 Y_4 \) is 75% at 1 bar and 600K. Find \( \Delta G^\circ \) of reaction in kJ/mol\(^{-1}\).

Hint:

When calculating \( \Delta G^\circ \) for reactions involving dissociation, first determine the equilibrium constant \( K \) using the degree of dissociation and then apply the formula \( \Delta G^\circ = -RT \ln K \).
