As per your syllabus, a reaction with ΔH < 0 AND ΔS > 0 is spontaneous under which condition?
AOnly at low T
BAt ALL temperatures
COnly at high T
DNever
Answer & Solution
Correct answer: B. At ALL temperatures
As per your syllabus, ΔH(−) + ΔS(+)
⇒ ΔG = ΔH − TΔS is always negative
⇒ spontaneous at all T.
