Calculate ΔG° (in kJ/mol)for the following reaction at 1 atm and 25°C:
C2H6 (g)+ O2 (g)→ CO2 (g)+ H2O (l)(unbalanced)
ΔHf° C2H6 (g)= -84.7 kJ/mol; S∘C2H6 (g)= 229.5 J/K ∙ mol;
ΔHf° CO2 (g)= -393.5 kJ/mol; S∘CO2 (g)= 213.6 J/K ∙ mol;
ΔHf° H2O (l)= -285.8 kJ/mol; S∘H2O (l)= 69.9 J/K ∙ mol;
S∘O2 (g)= 205.0 J/K ∙ mol
