Q31 · CSIR-NET Chemistry, June 2015

Paper: CSIR-NET June 2015 · Subject: Physical Chemistry · Chapter: Electrochemistry · Topic: Electrochemistry – General · Marks: 2 · Difficulty: Easy

The temperature-dependence of an electrochemical cell potential is

(a)$\frac{\Delta G}{n F T}$

(b)$\frac{\Delta H}{n F}$

(c)$\frac{\Delta S}{n F}$

(d)$\frac{\Delta S}{n F T}$

Answer

Answer: C ✓ checked by 4AB · confidence high

Explanation

ΔG = −nFE and (∂ΔG/∂T)p = −ΔS, so (∂E/∂T)p = ΔS/nF (c).
