ΔG is the net energy available to do useful work and is a measure of free energy. If a reaction has positive enthalpy change and positive entropy change, under what conditions will the reaction be spontaneous?
- DG will be positive at low temperature hence reaction is spontaneous at low temperature.
- DG is negative at high temperature hence reaction is spontaneous at high temperature.
- DG is negative at low temperature hence reaction is spontaneous at low temperature.
- DG is negative at all temperatures hence reaction is spontaneous at all temperatures.
Answer
(B) D G is negative at high temperature hence reaction is spontaneous at high temperature.
