A cell is prepared by dipping copper rod in 1 M copper sulphate solution and zinc rod in 1 M zinc sulphate solution. The standard reduction potential of copper and zin c are `0.34 V and - `0.76 V respectively.
(i) What will be the cell reaction ?
(ii) What will be the standard electromotive force of the cell ?
(iii) Which electrode will be positive ?

Explanation

To solve the problem step by step, we will address each part of the question systematically.

### Step 1: Determine the Cell Reaction

In the given electrochemical cell, we have:
- A copper rod in a 1 M copper sulfate solution (CuSO₄).
- A zinc rod in a 1 M zinc sulfate solution (ZnSO₄).
