A reaction has a positive entropy change. What would the sign of AHrxn need to be to make the spontaneity of the reaction temperature dependant? In this case, would the temperature have to decrease or increase to make it nonspontaneous? AHrxn > 0, temperature would have to increase to make the reaction nonspontaneous. AHTXN > 0, temperature would have to decrease to make the reaction nonspontaneous. Remove 5 points from my score, please. AHTXN < 0, temperature would have to decrease to make the reaction nonspontaneous.
