Q. When enthalpy and entropy change for a chemical reaction are $- 2.5 \times 10^{3}$ cal and 7.4 cal $\deg^{- 1}{respectively}$ predict the reaction at 298 K is

A) Spontaneous
B) Reversible
C) Irreversible
D) Non-spontaneous
Explanation

(a)
When $\mathrm{\Delta}H = - ve,\ \mathrm{\Delta}S = + ve$ and $\mathrm{\Delta}G = - ve$ than reaction is spontaneous
