Calculate ΔG° (in KJ/mol)for the Following Reaction at 1 Atm

question 33

Short Answer

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