19. Chemical Thermodynamics / Gibbs Free Energy And Equilibrium / Problem 20
Using the following data,
PN2 = PPH3 = 0.06 atm, PNH3= 0.3 atm, PP4 = 0.2 atm
ΔG°f, P4(g) = 24.4 kJ/mol, ΔG°f, NH3(g) = –16.4, ΔG°f, PH3(g) = 13.5 kJ/mol, ΔG°f, N2(g) = 0
calculate Kp and ΔG at 298 K for the reaction
4 PH3 (g) + 2 N2 (g) ⇌ P4 (g) + 4 NH3 (g)
