Question

Explain the limitations of the following expressions: (a) DS = C ln(T f /T i ), (b) DG = DH − TDS, and (c) DG= w max,non-exp .

Answer 1

(a) Limitations: Assumes reversible process, constant heat capacity.

(b) Limitations: Assumes constant T and P, and independent DH and DS with temperature.

(c) Limitation: Assumes non-expansion conditions, may not account for volume changes in real scenarios.
