  1. A केवल \(C\) तथा \(D\) 
  2. B केवल \(B\) तथा \(C\) 
  3. C केवल \(A\) तथा \(B\) 
  4. D केवल \(B\) तथा \(D\) 
Verified Solution

Answer & Solution

Correct Answer

(B) केवल \(B\) तथा \(C\) 

Step-by-step Solution

Detailed explanation

Only \((B)\) and \((C)\) are correct. \((B)\) \(G = H - TS\) At constant \(T\) \(\Delta G =\Delta H - T \Delta S\) (A) First law is given by \(\Delta U = Q + W\) If we apply constant \(P\) and reversible work \(\Delta U = Q - P \Delta V\) (C)By definition of entropy change…
