Statement 1: A reaction with Δ H>0 and Δ S<0 is spontaneous at all temperatures.
Statement 2: A reaction with Δ H<0 and Δ S>0 is spontaneous at all temperatures.
Options:
Answer:
D
Solution:
Δ H>0,Δ S<0: Δ G=Δ H+T|Δ S|>0 at every T, so the reaction is never spontaneous: I incorrect. Δ H<0,Δ S>0: Δ G=-|Δ H|-TΔ S<0 always: II correct. Answer (d).
