When sulphur in the form of $S_{8}$ is heated at 900 K the initial pressure of 1 atm falls by 29% at equilibrium. This is because of conversion of some $S_{8}$ to $S_{2}$ . Find the value of equilibrium constant for this reaction.

Options:

Answer:

Solution:

$\underset{\underset{1 - x}{1}}{S_{8} (g)} ⇌ \underset{\underset{4 x}{0}}{4 S_{2} (g)}$
$x = 29 % = 0.29$
$K_{p} = \frac{(P_{S_{2}})^{4}}{(P_{S_{8}})} = \frac{(4 x)^{2}}{(1 - x)} a t m^{3}$
$= \frac{(4 \times 0.29)^{4}}{1 - 0.29} = 2.55 a t m^{3}$ .
