Distinguish clearly between the meanings of `E_(cell)=0 and E_(cell)^@=0`

Explanation

To distinguish between the meanings of \( E_{\text{cell}} = 0 \) and \( E_{\text{cell}}^{\circ} = 0 \), we can break down the concepts as follows:

### Step-by-Step Solution:

1. **Understanding \( E_{\text{cell}}^{\circ} = 0 \)**:
- \( E_{\text{cell}}^{\circ} \) represents the standard cell potential of an electrochemical cell.
- When \( E_{\text{cell}}^{\circ} = 0 \), it indicates that both the anode and cathode half-cells have standard electrode potentials that are equal to zero.
- This means that there is no driving force for the redox reaction to occur under standard conditions (1 M concentration, 1 atm pressure, 25°C).
