ΔG = 2721.891 J/mol
Explanation:
C2H4(g) + H2O(g) ↔ C2H5OH(g)∴ ΔH°rxn = - 45.8 KJ/mol
∴ Kp = 28.5
If p(C2H4) = p(H2O) = p(C2H5OH) = 3.0 atm ⇒ ΔG°rxn = ?
⇒ Kp = (PC2H5OH/P*) / (PC2H4/P*)(PH2O/P*)
∴ P* = 1 atm
⇒ Kp = (3 atm) / (3 atm)(3 atm) = 0.33
Kp = e∧( - ΔG/RT)⇒ Ln Kp = - ΔG/RT
⇒ ΔG = - RT LnKp
∴ T = 298 K
∴ R = 8.314 J/mol.K
⇒ ΔG = - ((8.314 J/mol.K)(298 K)) Ln(0.33)
⇒ ΔG = 2721.891 J/mol
