Statement 1: Many endothermic reactions that are not spontaneous at room temperature become spontaneous at high temperature.
Statement 2: Entropy of the system increases with increase in temperature.
Options:
Answer:
A
Solution:
For Δ H>0, Δ S>0, Δ G=Δ H-TΔ S becomes negative once T>Δ H/Δ S: I correct. Entropy of a system rises with T (dS=C dT/T>0), so the TΔ S term grows and finally outweighs Δ H. II is correct and is the reason. Answer (a).
