Question

For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species.

2NO(g)+O2->2NO2(g)

For the reactionthe standard change in Gibbs free energy is ΔG° = -69.0 kJ/mol. What is ΔG for this reaction at 298 K when the partial pressures are

P NO: .350 atm P O2: .500 atm

PNO2: .700 atm

delta G in kj/mol
