Write the disproportionate reaction of `MnO_(4)^(2-)` ?

Explanation

To write the disproportionation reaction of \( \text{MnO}_4^{2-} \), we will follow these steps:

### Step 1: Understand Disproportionation Reaction
A disproportionation reaction is a type of redox reaction where a single species is simultaneously oxidized and reduced, resulting in two different products.

### Step 2: Determine the Oxidation State of Manganese in \( \text{MnO}_4^{2-} \)
To find the oxidation state of manganese in \( \text{MnO}_4^{2-} \):
- Let the oxidation state of manganese be \( x \).
