Question

Example: AG from Table Use data from Appendix C to calculate AG for the combustion of methane. CH4(g) 2 O2 CO2(g) 2 H2O(g)

Answer 1

Answer #1

dG rxn = dGf products - dGf reactants

dGf of CH4 = - 50.72 kJ/mol

dGf of O2 = 0 kJ/mol

dG of CO2 = -394.359 kJ/mol

dG of H2O = -228.572 kJ/mol

dGrxn = 1*-394.359 + 2*-228.572 - (1*-50.72 +1*0)

dGrxn = - 851.503 + 50.72

dGrxn = -800.78 kJ/mol
