Chemistry - Thermodynamics - II Question with Solution | TestHub

Consider the following reaction approaching equilibrium at $27°\mathrm{C}$ and $1$ atm pressure

$\mathrm{A}+\mathrm{B}\underset{{\mathrm{k}}_{\mathrm{b}}={10}^2}{\stackrel{{\mathrm{k}}_{\mathrm{f}}=0^3}{\rightleftharpoons }}\mathrm{C}+\mathrm{D}$

The standard Gibb's energy change $\left({\mathrm{\Delta }}_{\mathrm{r}}\mathrm{G}°\right)$ at $27°\mathrm{C}$ is $\left(-\right)$ _____ ${\mathrm{kJmol}}^{-1}$ (Nearest integer).

(Given : $\mathrm{R}=8.3\mathrm{J} {\mathrm{K}}^{-1} {\mathrm{mol}}^{-1}$ and $\ln 10=2.3$)
