Make sure to show all of your work.     Consider the following reaction:  NH4NO3(s) →  NH4+(aq) +NO3-(aq) a) Calculate the standard enthalpy change for this reaction at 25°                                                  b) Calculate the standard entropy change for this reaction at 25°                                                    c) Calculate the standard Gibbs free energy change for this reaction at 25°                                    d) What can be said about the spontaneity of this reaction at 25°C? (circle one)                               The reaction is not spontaneous at any temperature The reaction is spontaneous at all temperatures The reaction will only be spontaneous at low temperatures The reaction will only be spontaneous at high temperatures e)  Let’s just say, ΔHº = -241.8 kJ and ΔSº = -88.8 J K-1.  (Ignore ΔGº). Assuming that ΔHº = ΔH and ΔSº = ΔS at all temperatures, calculate the temperature criterion for spontaneity.  That is, indicate the minimum or maximum temperature required for spontaneity (e.g. T > ### or T
