Question

under what conditions will a low temperature make a reaction spontaneous?

Answer 1

Answer:

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 positive, and –TΔS negative, the reaction will be spontaneous at high temperatures (increasing the magnitude of the entropy term).

Answer 2

Answer:

At a relatively low temperature (below 273 K), the melting is not spontaneous because the positive ΔH term “outweighs” the TΔS term. When the temperature rises above 273 K, the process becomes spontaneous because the larger T value has tipped the sign of ΔG over to being negative.
