# Question: Using data from Appendix 4 calculate Ho So and K

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.
