What Type Of Reaction Is Always Spontaneous?

by

What Type Of Reaction Is Always Spontaneous? A reaction which is exothermic (ΔH negative) and results in an increase in the entropy of the system (ΔS positive) will always be spontaneous. Which chemical reaction is always spontaneous? A reaction which is exothermic (ΔH negative) and results in an increase in the entropy of the system

At What Temperature Does The Reaction Change From Spontaneous To Nonspontaneous? c)The reaction changes between spontaneous and nonspontaneous at approximately 1518 K. At what temperature will the reaction become spontaneous? If ΔH is negative, and –TΔS positive, the reaction will be spontaneous at low temperatures (decreasing the magnitude of the entropy term). If ΔH is
