Solution
For a galvanic cell involving the cell reaction
\[\ce{aA + bB -> cC + dD}\]
The Nernst equation can be written as follows.
\[\ce{E_{cell} = E{^{\circ}_{cell}} - \frac{RT}{nF} log_e \frac{[C]^c[D]^d}{[A]^a[B]^b}}\]
At T = 298 K (25°C), we have
\[\ce{E_{cell} = E{^{\circ}_{cell}} - \frac{0.0591}{n} log_e \frac{[C]^c[D]^d}{[A]^a[B]^b}}\]
