For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species. For the reaction C2H6 (g)+ H2 (g) -> 2CH4
the standard change in Gibbs free energy is ?G° = -69.0 kJ/mol. What is ?G for this reaction at 298 K when the partial pressures are
PC2H6 0.15 atm, PH2 0.15 atm, and PCH4 0.75
What is the delta G in kJ/mol?
