Statement 1: A reaction with Δ H<0 and Δ S<0 is more likely to be spontaneous at low temperature.
Statement 2: For such a reaction, Δ G becomes more negative as the temperature increases.
Options:
Answer:
C
Solution:
Δ G=Δ H-TΔ S=Δ H+T|Δ S|. Lowering T lowers the positive term, so Δ G is more likely negative: I correct. As T rises, Δ G becomes less negative (more positive): II incorrect. Answer (c).
