For the reaction $2{\mathrm{SO}}_2(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})\rightleftharpoons 2{\mathrm{SO}}_3(\mathrm{g})$ at 298 K, $K_p=2.0\times 10^{24}$. The standard free energy of formation of ${\mathrm{SO}}_2(\mathrm{g})$ is -300 kJ/mol at 298 K. What is the standard free energy of formation of ${\mathrm{SO}}_3(\mathrm{g})$ at 298 K (in J/mol)?
