# Determination of Cell Potential from an Ion Concentration

CHEM-IJX0RH

Use the table of reduction potentials.

Consider the cell described below:

$$\textrm{Cr}|\textrm{Cr}^{3+} (0.600 \textrm{ M}) || \textrm{Pb}^{2+} (0.400 \textrm{ M})|\textrm{Pb}$$

Calculate the cell potential after the reaction has operated long enough until $\left[\textrm{Pb}^{2+}\right]$ is $0.300 \textrm{ M}$ at $298 \textrm{ K}$.

A

$0.594 \textrm{ V}$

B

$0.606 \textrm{ V}$

C

$0.614 \textrm{ V}$

D

$0.618 \textrm{ V}$

E

$0.858 \textrm{ V}$
