Consider the following reactions:
(i) `Fe+CuSO_(4)rarrFeSO_(4)+Cu`
(ii) `Cu+FeSO_(4)rarrCuSO_(4)+Fe`
Which of these two reactions will take place and why?

Explanation

To determine which of the two reactions will take place, we need to refer to the metal activity series. The metal activity series ranks metals based on their reactivity, with more reactive metals being able to displace less reactive metals from their compounds.

### Step-by-Step Solution:

1. **Identify the Reactions**:
- Reaction (i): `Fe + CuSO₄ → FeSO₄ + Cu`
- Reaction (ii): `Cu + FeSO₄ → CuSO₄ + Fe`
