The temperature at which the reaction,

\mathrm{A}{\mathrm{g}_2}\mathrm{O}\left( s \right) \to 2\mathrm{Ag}\left( s \right) + \frac{1}{2}{\mathrm{O}_2}\left( \mathrm{g} \right)

Is at equilibrium is …;gives,

\Delta H = 30.5\,\,\;\mathrm{kJ\;mo}{\mathrm{l}^{ - 1}}

and 

\Delta S = 0.066\,\;\,\mathrm{kJ\;}\,{\mathrm{K}^{ - 1}}\mathrm{mo}{\mathrm{l}^{ - 1}}

View answer and explanation

Correct option: A

462.12 K

Option A (462.12 K) is correct because it is the temperature at which Δ G = 0, calculated using the Gibbs free energy equation.
