JEE PYQ: Electrochemistry Question 17
Question 17 - 2020 (05 Sep Shift 1)
An oxidation-reduction reaction in which 3 electrons are transferred has a $\Delta G^0$ of 17.37 kJ mol$^{-1}$ at 25$^\circ$C. The value of $E^0_{\text{cell}}$ (in V) is ____ $\times 10^{-2}$.
$(1$ F $= 96,500$ C mol$^{-1})$
Show Answer
Answer: -6
Solution
$E^0_{\text{cell}} = \frac{-\Delta G^0}{nF} = \frac{-17370}{3 \times 96500} = -0.06$ V $= -6 \times 10^{-2}$ V.
