The standard molar Gibbs free energy of formation of NO2 (g) at 298 K is 51.30 kJ · mol
and that of N2O4 (g) is 97.82 kJ · mol
What is the equilibrium constant at 25
2 NO2(g) <=> N2O4(g) ?
dGrxn = (n*dGproducts) - (n*dGreactants)
Substitute and solve for dGrxn, then
dG = -RT*lnK
Substitute and solve for K
