Question:
For the chemical reaction $\mathrm{X} \rightleftharpoons \mathrm{Y}$, the standard reaction Gibbs energy depends on temperature $\mathrm{T}$ (in $\mathrm{K}$ ) as :
$\Delta_{\mathrm{r}} \mathrm{G}^{\circ}\left(\right.$ in $\left.\mathrm{kJ} \mathrm{mol}^{-1}\right)=120-\frac{3}{8} \mathrm{~T}$
The major component of the reaction mixture at $T$ is :
Correct Option: 1
Solution:
$\mathrm{X}$ if $\mathrm{T}=315 \mathrm{~K}$
