Calculate ΔG° (in kJ/mol) for the following reaction at 1 atm and 25 °C:
C2H6 (g) + O2 (g) → CO2 (g) + H2O (l) (unbalanced)
ΔGf° C2H6 (g) = -32.89 kJ/mol; ΔGf° CO2 (g) = -394.4 kJ/mol; ΔGf° H2O (l) = -237.13 kJ/mol
Homework Answers
C2H6 + 7/2 O2 -------------> 2CO2 + 3H2O is the balanced equation
thus Delta G rxn = [sum of DG of products]- [ sum of Dg of reactants]
= [ 2x(-394.4) + 3 (-237.13)] - [ 1(-32.89 ) + 7/2(0)]
= -1467.3 kJ /mol
