Question

Match the following

Column I Column II

(A) Standard free energy change (p) $n R ln \frac{V_{2}}{V_{1}}$

(B) Enthalpy change (q) $- R T ln K$

(C) Entropy change (r) $Δ E + P Δ V$

(D) Free energy change (s) $- n F E$

(t) $Δ U + Δ n g R T$

Open in App

Solution

(A) We know that

$Δ G = Δ G^{\circ} + R T ln K$
at equilibrium

$Δ G = 0$
$\Rightarrow Δ G^{\circ} = - R T ln K$
(B) $H = E + P V$
$Δ H = Δ E + P Δ V + V Δ P$

at constant pressure

$Δ P = 0$
$\Rightarrow Δ H = Δ E + P Δ V$
$Δ S = \frac{Q_{R e v}}{T} = \frac{n R T l n \frac{V_{2}}{V_{1}}}{T} = n R ln \frac{V_{2}}{V_{1}}$

(D) Negative of free energy change

= work done $= Q V$
$- Δ G = (n F) E$
$Δ G = - n F E$
