The standard molar entropies of

\mathrm{H}_2(\mathrm{~g}), \mathrm{N}_2(\mathrm{~g})

and

\mathrm{NH}_3(\mathrm{~g})

are 130,190 and

193 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}

respectively. For the reaction

1 / 2 \mathrm{~N}_2(\mathrm{~g})+3 / 2 \mathrm{H}_2(\mathrm{~g}) \rightleftharpoons \mathrm{NH}_3(\mathrm{~g}) \left(\Delta \mathrm{H}_{\text {reaction }}=-45 \mathrm{~kJ}\right) to be in equilibrium, the temperature must be equal to
