What will be the effect of increasing pressure on the following equilibria ?
` 2Hl (g) hArr H_2(g) +I_2(g)`

Explanation

To determine the effect of increasing pressure on the equilibrium of the reaction \(2 \text{HI} (g) \rightleftharpoons \text{H}_2 (g) + \text{I}_2 (g)\), we can apply Le Chatelier's principle. Here’s a step-by-step solution:

### Step 1: Identify the reaction and its components
The given equilibrium reaction is:
\[ 2 \text{HI} (g) \rightleftharpoons \text{H}_2 (g) + \text{I}_2 (g) \]
In this reaction:
