The heat of formation of MgO at 300 K and 1 bar pressure is $-600.60 \mathrm{kJ} \mathrm{mol}^{-1}$. The free energy (in $\mathrm{kJ} \mathrm{mol}^{-1}$ ) of formation of MgO at 280 K is ____ (Round off to nearest integer) Given: In the range $280-300 \mathrm{K}$, the constant pressure heat capacities $\left(\mathrm{C}_{\mathrm{P}}\right)$ and molar entropies $\left(\mathrm{S}_{\mathrm{m}}\right)$ are:
