- For the following reaction at 298K, if the flask contains 25 g NH4Cl, 1.2 atm NH3 and 1.8 atm HCl, then what is the free energy for the reaction under these conditions?
NH4Cl (s) <----> NH3 (g) + HCl (g) Kp= 3.06 (at 298K)
CORRECT ANSWER: -0.863 kJ
-NH4NO (s) <---> NH4+ (aq) + NO3- (aq)
Species (delta) H (kJ/mol) (delta) G (kJ/mol)
NH4NO3 -367.56 -183.87
NH4+ -132.5 -79.31
NO3- -205.0 -108.7
