Assuming that, since the physical states do not change, the values of ΔH and ΔS do not change as we raise the temperature in the reaction below. Using the following values at 298 K
CdO(s), ΔHဢထ = -258.2 kJ mol⁻¹, Sဢ = +54.8 J mol⁻¹ K⁻¹
CdSO₄ (s), ΔHဢထ = -933.5 kJ mol⁻¹, Sဢ = +123 J mol⁻¹ K⁻¹
SO₃ (g), ΔHဢထ = -396 kJ mol⁻¹, Sဢ = +256 J mol⁻¹ K⁻¹
calculate a value for the free energy change, ΔGₒ for the reaction,
CdSO₄ (s) → CdO(s) + SO₃ (g) at 750 K
A. +223.3 kJ
B. +138.5 kJ
C. +296.0 kJ
D. +420.5 kJ
E. all the above
F. none of the above
