Question
For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species.
For the reaction
N, (g) + 3 H, (g) = 2 NH,(g)
the standard change in Gibbs free energy is AG° = –72.6 kJ/mol. What is AG for this reaction at 298 K when the partial
pressures are PN,
= 0.500 atm, PH,
= 0.500 atm, and PNH, = 0.600 atm?
AG =
kJ/mol
