For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 bar for all species.
For the reaction
2 NO(g) + O₂(g) = 2 NO₂(g)
the standard change in Gibbs free energy is AG -69.0 kJ/mol. What is AG for this reaction at 298 K when the partial
pressures are PNO = 0.250 bar, Po₂ = 0.400 bar, and PNO₂ = 0.850 bar?
