Which of the two peroxide ion or superoxide ion has larger bond length ?

Explanation

To determine which ion has a larger bond length between the peroxide ion (O2^2-) and the superoxide ion (O2^-), we will analyze their bond orders. The bond length is inversely proportional to the bond order, meaning that a higher bond order corresponds to a shorter bond length.

### Step-by-Step Solution:

1. **Identify the Ions**:
- Peroxide ion: O2^2-
- Superoxide ion: O2^-
