Question

For a certain chemical reaction, DH is > 0 and DS is < 0. This means that Question 6 options: 1) we conclude the reaction must be non-spontaneous regardless of temperature and becomes even more so at higher temperatures 2) we conclude the reaction must be spontaneous regardless of temperature and becomes even more so at lower temperatures 3) we conclude the reaction may or may not be spontaneous, but spontaneity is favored by low temperatures. 4) we conclude the reaction may or may not be spontaneous, but spontaneity is favored by high temperatures. 5) we cannot make any conclusion about spontaneity or even tendencies from the limited information presented.

Explanation / Answer

G=H-TS

H>0 and S<0

G is always >0 and becomes more positive as T increases.
