When `S` in the form of `S_(8)` is heated at `900 K`, the initial pressure of `1 atmosphere` falls by `29%` at equilibrium. This is because of conversion of some `S_(8)` to `S_(2)`. Find the `K_(p)` for reaction.

Explanation

To find the equilibrium constant \( K_p \) for the reaction where sulfur \( S_8 \) converts to \( S_2 \) at 900 K, we can follow these steps:

### Step 1: Write the balanced chemical equation

The balanced reaction for the conversion of sulfur \( S_8 \) to \( S_2 \) is:
\[ S_8 \rightarrow 4 S_2 \]
