Practice Problem 6
Calculate H° and S° for the following reaction:
NH4NO3(s) + H2O(l) NH4+ (aq) + NO3- (aq)
Use the results of this calculation to determine the value of Go for this reaction at 25o C, and explain why NH4NO3 spontaneously dissolves is water at room temperature.
Ho = 28.05 kJ
So = 108.7 J/K
Go = -4.4 kJ
