The variation of equilibrium constant with temperature is given below :
The values of $\displaystyle \Delta \mathrm{H}^{\circ}, \Delta \mathrm{G}^{\circ}$ at $\displaystyle \mathrm{T}_1$ and $\displaystyle \Delta \mathrm{G}^{\circ}$ at $\displaystyle \mathrm{T}_2$ (in $\displaystyle \mathrm{kJ} \mathrm{mol}^{-1}$ ) respectively, are close to [use $\displaystyle \mathrm{R}=8.314 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ ]
| Temperature | Equilibrium Constant |
| $\displaystyle \mathrm{T}_1=25^{\circ} \mathrm{C}$ | $\displaystyle \mathrm{K}_1=10$ |
| $\displaystyle \mathrm{T}_2=100^{\circ} \mathrm{C}$ | $\displaystyle \mathrm{K}_2=100$ |
