For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species. For the reaction
N2(g)+3H2(g)=2NH3
the standard change in Gibbs free energy is ?G° = -32.8 kJ/mol. What is ?G for this reaction at 298 K when the partial pressures are
P C2H6=0.100atm, P H2=0.100atm and P CH4=.750atm
