For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 bar for all species. For the reaction
C2H6(g)+H2(g)---->2CH4
the standard change in Gibbs free energy is ΔG = -32.8 kJ/mol. What is ΔG for this reaction at 298 K when the partial pressures are
P(C2H6)=0.500bar, P(H2)=0.500bar, and P(CH4)=0.850bar
dG=____kj/mol
