NEET levelSingle correct optionDifficulty 1 of 3td174

A reaction has $Δ H < 0$ and $Δ S > 0$ . It is

Aspontaneous at all temperatures
Bspontaneous only at low temperatures
Cspontaneous only at high temperatures
Dnon-spontaneous at all temperatures

Answer: A

Δ G = Δ H - T Δ S

. Here

Δ H

is negative and

- T Δ S

is also negative at every

T

, so

Δ G < 0

at all temperatures.
