Chemistry - Thermodynamics - II Question with Solution | TestHub

The ratio of equilibrium constants $\left(\frac{{\mathrm{K}}_{1000}}{{\mathrm{K}}_{500}}\right)$ for the reaction : $\mathrm{A}(\mathrm{g})+\mathrm{B}(\mathrm{g})\rightleftharpoons$ product, at temperature 500 K and 1000 K is ${\mathrm{e}}^{50}$. Find the equilibrium entropy change ( $\mathrm{cal}/\mathrm{mol}-\mathrm{K}$ ) of above reaction at 1000 K if the reaction is at equilibrium at 1000 K , at standard conditions. Assume that enthalpy change of reaction is temperature independent. ( $\mathrm{R}=2\mathrm{cal}/\mathrm{mol}-\mathrm{K}$ )
