Redox Reactions And Electrochemistry Ques 173

Question: For the cell reaction $C u^{2 +} (C_{1} a q) + Z n (s) = Z n^{2 +} (C_{2} a q) + C u (s)$ of an electrochemical cell, the change in free energy at a given temperature is a function of [CBSE PMT 1998]

Options:

A) ln $(C_{1})$

B) ln $(C_{2})$

C) ln $(C_{1} + C_{2})$

D) ln $(C_{2} / C_{1})$

Show Answer

Answer:

Correct Answer: D

Solution:

$E_{c e l l} = E_{c e l l}^{o} - \frac{R T}{n F} \ln \frac{C_{2}}{C_{1}}$ and $Δ G = - n F, E_{c e l l}$ hence $Δ G$ is the function of $\ln, (\frac{C_{2}}{C_{1}})$ .
