An exаmple оf а reаctiоn that experiences a decrease in entrоpy, ΔS < 0, yet is spontaneous because of the release of a large quantity of heat, ΔH = −151 kJ, is the formation of solid ammonium nitrate from the reaction of gaseous nitric acid with gaseous ammonia.                        HNO3(g)   +   NH3(g)   →  NH4NO3 (s)       ΔG° =  −93. kJ/mol.  Calculate the equilibrium constant, K, for the reaction at T = 298 K.
