Question

The thermodynamic efficiency of cell is given by –

• A. ∆H/∆G
• B. nFE/∆G
• C. nFE/∆H
• D. Nfe⁰

Answer 1

Answer: (C)

nFE/∆H

Answer 2

Thermodynamic efficiency = $\frac{nFE}{\Delta H}$, i.e., the part of enthalpy change during the course of redox reaction, given out as electrical energy.
