Using data from Appendix 4, calculate Ho, So, and K (at 298 K) for the synthesis of ammonia by the Haber process: N2(g) + 3H2(g)

Using data from Appendix 4, calculate ΔHo, ΔSo, and K (at 298 K) for the synthesis of ammonia by the Haber process:
N2(g) + 3H2(g) ⇌ 2NH3(g)
Calculate ΔG for this reaction under the following conditions (assume an uncertainty of 61 in all quantities):
a. T = 298 K, PN2 = PH2 = 200 atm, PNH3 = 50 atm
b. T = 298 K, PN2 = 200 atm, PH2 = 600 atm, PNH3 = 200 atm
c. T = 100 K, PN2 = 50 atm, PH2 = 200 atm, PNH3 = 10 atm
d. T = 700 K, PN2 = 50 atm, PH2 = 200 atm, PNH3 = 10 atm
Assume that ΔHo and ΔSo do not depend on temperature.
