The value of `K_(c)` for the reaction: `H_(2)(g)+I_(2)(g) hArr 2HI (g)` is 48 at 773 K. If one mole of `H_(2)`, one mole of `I_(2)` and three moles of HI are taken in a 1L falsk, find the concentrations of `I_(2)` and HI at equilibrium at 773 K.

Explanation

To solve the problem step by step, we will follow these instructions:

### Step 1: Write the balanced chemical equation and the expression for \( K_c \)

The balanced chemical equation is:
\[ H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \]

The expression for the equilibrium constant \( K_c \) is given by:
