What can be said about an endothermic reaction with a negative entropy change?
spontaneous in the reverse direction at all temperatures.
What can be said about an exothermic reaction with a negative entropy change?
spontaneous at low temperatures.
If ?H = -70.0 kJ and ?S = -0.300 kJ/K , the reaction is spontaneous below a certain temperature. Calculate that temperature.
A reaction in which the entropy of the system increases can be spontaneous only if it is exothermic.
false
A reaction in which the entropy of the system increases can be spontaneous only if it is endothermic.
