Consider the following reaction approaching equilibrium at 27°C and 1 atm pressure
$\mathrm{A}+\mathrm{B}\underset{{\mathrm{k}}_{\mathrm{r}}={10}^2}{\overset{{\mathrm{k}}_{\mathrm{j}}={10}^2}{\rightleftharpoons }}\mathrm{C}+\mathrm{D}$
The standard Gibb’s energy change $\left(\mathrm{\Delta },{\mathrm{G}}^0\right)$ at 27°C is (-) _________kJ^-1
(Nearest integer)
(Given: $\mathrm{R}=8.3{\mathrm{JK}}^{-1}{\mathrm{moI}}^{-1}\text{ and In }10=2.3)$
