Question

At $700 K$ , equilibrium constant for the reaction: $H_{2} (g) + I_{2} (g) ⇌ 2 H I (g)$ is $64$ . If $0.5 m o l$ $L^{- 1}$ of $H I (g)$ is present at equilibrium at $700 K$ , what are the concentration of $H_{2} (g)$ and $I_{2} (g)$ assuming that we initially started with $H I (g)$ and allowed it to reach equilibrium at $700 K$ ?

Solution

The correct option is C $0.0625 M$
$H_{2} (g) + I_{2} (g) ⇌ 2 H I (g) K = 64, T = 700 K$
$2 H I ⇌ H_{2} + I_{2} K = 1 / 64700 K$
$a$ $0$ $0$
$a (1 - α)$ $a α / 2$ $a α / 2$
$0.5$ $x$ $x$ $x$ be concentration
$\frac{x^{2}}{{(0.5)}^{2}} = \frac{1}{64} x = 1 / 16$
$x = 0.0625$
