For the equilibrium $H_{2} (g) + CO_{2} (g) ⇌ H_{2} O (g) + CO (g), K_{c} = 16$ at 1000 K . If 1.0 mole of $CO_{2}$ and 1.0 mole of $H_{2}$ are taken in a 1 L flask, the final equilibrium concentration of CO at 1000 K will be

Options:

Answer:

Solution:

H₂(g) + CO₂(g) $⇌$ H₂O(g) + CO(g)

1 – x 1 – x x x

$K_{c} = \frac{x ^{2}}{( 1 - x ) ^{2}} = 16$

Taking the square root of both sides:

$\frac{x}{1 - x} = 4$

$x = 4 - 4 x$

$5 x = 4$

$x = \frac{4}{5} = 0.8 M$
