Calculate ΔG for this reaction under the following conditions (assume an uncertainty of 1 in all quantities, calculate all thermodynamic values from Appendix 4 for all parts of the problem).
(a) T = 275 K, PN2 = PH2 = 190 atm, PNH3 = 50. atm
(b) T = 275 K, PN2 = 197 atm, PH2 = 570 atm, PNH3 = 200. atm
