Calculate the standard change in Gibbs free energy for the following reaction at 25 degree C. Use the Delta G degree_f values found in the Chempendix. Delta G degree _rxn =
Expert Answer
Answer
GRxn = G-products – G-reactants
Subtitute
Grxn = 4*CO2 + 6*H2O – (2*C2H6 + 7*O2)
substitute data
GRxn = 4*(-394.4) + 6*(-228.6) – (2*(-32.0) + 7*0)
Grxn = -2,885.2 kJ/mol
