Question

Given, \( \Delta G^\circ = -nFE_{\text{cell}} \) and \( \Delta G^\circ = -RT \ln K \). The value of \( n = 2 \) will be given by the slope of which line in the figure

• A. OA
• B. OB
• C. OC
• D. OD

Hint:

The slope of the \( \Delta G^\circ \) vs \( \ln K \) plot gives the value of \( -nF \), and the slope represents the number of electrons involved in the reaction.

Answer 1

The Correct Option is B

In this problem, the slope of the graph between \( \Delta G^\circ \) and \( \ln K \) is \( -nF \). For the given condition, the slope corresponding to \( n = 2 \) is represented by the line \( OB \) in the graph.
