Derive expression to calculate emf (reduction) of the following half cells at `25^@C`
`AgCl(s),Cl^(-)|Ag`

Explanation

To derive the expression for the electromotive force (emf) or reduction potential of the half-cell reaction involving silver chloride (AgCl), we will follow these steps:

### Step 1: Write the half-reaction
The half-reaction for the reduction of silver chloride can be written as:
\[ \text{AgCl(s)} + e^- \rightarrow \text{Ag(s)} + \text{Cl}^-(aq) \]
