Q3.
Question Three: (8 points) (1) (5 points) At constant pressure, an acid dissolves spontaneously in water, the solution gets hot. What is the sign of the enthalpy change for this process? From the given information, is it possible to predict the sign of AS for the process? Explain your answer. (2) (3 points) Indicate whether the forward reaction tends to be spontaneous at low temperatures, spontaneous at high temperatures, spontaneous at all temperatures, or non-spontaneous at all temperatures. Explain your answer. 4 NH3(g) + 5 O₂(g) → 4 NO(g) + 6 H₂O(g) AH < 0
