Explanation

To arrange the steps involved in the preparation of sodium hydroxide by the Castner process in the correct sequence, we can follow these steps:

### Step-by-Step Solution:

1. **Step (e)**: `2NaCl → 2Na^+ + 2Cl^-`
- This is the first step where sodium chloride (NaCl) is dissociated into sodium ions (Na^+) and chloride ions (Cl^-).

2. **Step (i)**: `2Cl^- → Cl_2 + 2e^-`
