Chemistry - Thermodynamics - II Question with Solution | TestHub

For the reaction ${\mathrm{N}}_2{\mathrm{O}}_4(\mathrm{g})\rightleftharpoons 2{\mathrm{NO}}_2(\mathrm{g}),\Delta {\mathrm{H}}^{\circ }=57.5\mathrm{kJ}$ and $\Delta {\mathrm{S}}^{\circ }=174{\mathrm{JK}}^{-1}$. Determine the temperature at which an equilibrium mixture of ${\mathrm{N}}_2{\mathrm{O}}_4$ and ${\mathrm{NO}}_2$ with a total pressure 20 atm contains equal moles of ${\mathrm{NO}}_2$ and ${\mathrm{N}}_2{\mathrm{O}}_4$.
