An example of a reaction that experiences a decrease in entropy, 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) The change in free energy under standard condition is: ΔG° = −93. kJ/mol. Calculate the equilibrium constant, K, for the reaction at T = 298 K.
