(I) What is the equilibrium constant expression for: 2 AgNO3(aq) + 2 NaOH(aq) ? Ag2O(s) + 2 NaNO3(aq) + H2O(l)?

Select one:

A) (Ag2O)(NaNO3)^2(H2O)/(AgNO3)^2 (NaOH)^2

B) (NaNO3)^2/(AgNO3)^2 (NaOH)^2

C) (AgNO3)^2 (NaOH)^2/(Ag2O)(NaNO3)^2(H2O)

D) (AgNO3)^2 (NaOH)^2/(NaNO3)^2

(II) The standard Gibbs free energy for N2O4(g) ? 2 NO2(g) is ΔG° = +4.73 kJ/mol at 298 K. What is the value of ΔG when P(N₂O₄)= 0.80 bar and P(NO₂)= 2.10 bar? (please include units in answer)

(III) True or False: For the problem above (The standard Gibbs free energy for N₂O₄(g) ? 2 NO₂(g) is ΔG° = +4.73 kJ/mol at 298 K. What is the value of ΔG when P(N₂O₄)= 0.80 bar and P(NO₂)= 2.10 bar) the reaction is spontaneous.
