Solutions

Expert Solution

ΔH∘rxn=− 132 kJ ; ΔS∘rxn= 260 J/K = 0.26KJ/K; T= 310 K

ΔG∘rxn     = ΔH∘rxn - TΔS∘rxn

                 = -132-310*0.26   = -212.6KJ

ΔH∘rxn= 132 kJ ; ΔS∘rxn=− 260 J/K = -0.26KJ/K; T= 310 K

ΔG∘rxn     = ΔH∘rxn - TΔS∘rxn

                 = 132-310*-0.26   =212.6KJ

ΔH∘rxn=− 132 kJ ; ΔS∘rxn=− 260 J/K = -0.26KJ/K ; T= 310 K

ΔG∘rxn     = ΔH∘rxn - TΔS∘rxn

                = -132-310*-0.26   = -51.4KJ

ΔH∘rxn=− 132 kJ ; ΔS∘rxn=− 260 J/K   = -0.26KJ/K; T= 563 K

ΔG∘rxn     = ΔH∘rxn - TΔS∘rxn

                = -132-563*-0.26   = 14.38KJ
