25mL of hydrogen and 18mL of iodine when heated in a closed container, produced 30.8mL of HI at equilibrium. Calculate the degree of dissociation of HI at the same temperature.

Explanation

To solve the problem of calculating the degree of dissociation of hydrogen iodide (HI) at equilibrium, we can follow these steps:

### Step-by-Step Solution:

1. **Write the Balanced Reaction:**
The balanced chemical reaction for the formation of hydrogen iodide from hydrogen and iodine is:
\[
H_2(g) + I_2(g) \rightleftharpoons 2 HI(g)
