For the reaction, 2SO 2_22​ + O 2_22​ ⇌ 2SO 3_33​, the equilibrium constant K p_pp​ = 5.0 at 207 °C. If the partial pressures of SO 2_22​, O 2_22​ and SO 3_33​ are 1.0×10−31.0 \times 10^{-3}1.0×10−3, 0.20 and 1.0×10−41.0 \times 10^{-4}1.0×10−4, respectively, then the Gibbs free energy of the reaction (ΔrG\Delta_r GΔr​G) in kJ mol −1^{-1}−1 at 207 °C is ‾\underline{\hspace{2cm}}​ [Given: R = 8.314 J K −1^{-1}−1 mol −1^{-1}−1]
