Question

What is the ideal condition for a reaction occuring on its own?
(A) TΔS = ΔH, ΔH = +ve ΔS = +ve
(B) TΔS = ΔH, ΔH = -ve ΔS = -ve
(C) TΔS > ΔH, ΔH = +ve ΔS = +ve
(D) TΔS > ΔH, ΔH = +ve ΔS = -ve

Answer 1

answer=(c)

Since ΔG=ΔH-TΔS

for reaction to occur ΔG is to be negative

so if ΔS is positive and ΔH is positive then TΔS>ΔH
