Question

For a certain chemical reaction, H is < 0 and Sis < 0. This means that

we cannot make any conclusion about spontaneity or eventendencies from the limited information presented.

we conclude the reaction may or may not be spontaneous, butspontaneity is favored by low temperatures.

we conclude the reaction may or may not be spontaneous, butspontaneity is favored by high temperatures.

we conclude the reaction must be spontaneous regardless oftemperature and becomes even more so at higher temperatures.

we conclude the reaction must be spontaneous regardless oftemperature and becomes even more so at lower temperatures.

we cannot make any conclusion about spontaneity or eventendencies from the limited information presented.

Explanation / Answer

When deltaH and deltaS are negative, your reaction isspontaneous at low temperatures because: deltaG = deltaH -TdeltaSand you want deltaG to be negative for a reaction to bespontaneous.
