Verified Solution

Answer & Solution

Correct Answer

(C) \(2\)

Step-by-step Solution

Detailed explanation

\(\Delta G =\Delta H - T \Delta S\) \(A : \Delta G \left( J\,mol ^{-1}\right)=-25 \times 10^3+80 \times 300:- ve\) \(B : \Delta G \left( J\,mol ^{-1}\right)=-22 \times 10^3-40 \times 300:- ve\) \(C : \Delta G \left( J\,mol ^{-1}\right)=25 \times 10^3+300 \times 50:+ ve\)…
