For the reaction `H_(2) + I_(2) hArr 2 HI, " if intially 25 mL of "H_(2) and 20 " mL of "I_(2)` are present ia a container in a container and at equilibrium, 30 mL of HI is foprmed , then calculate equilibrium constant.

Explanation

To calculate the equilibrium constant (K) for the reaction \( H_2 + I_2 \rightleftharpoons 2 HI \), we will follow these steps:

### Step 1: Write the balanced equation
The balanced chemical equation for the reaction is:
\[ H_2 + I_2 \rightleftharpoons 2 HI \]

### Step 2: Identify initial volumes
Initially, we have:
