$SO_{3} (g)$ is heated in a closed vessel. An equilibrium:

$2 S O_{3} (g) ⇌ 2 S O_{2} (g) + O_{2} (g)$

is established. The vapor density of the mixture, in which $S O_{3}$ is 50% dissociated, is:

Answer:

Solution:

$2 S O_{3} ⇌ 2 S O_{2} + O_{2}$

$(1 - α) α \frac{α}{2}$

$α = 2 (\frac{D - d}{d})$

$0.5 = 2 (\frac{40 - d}{d})$

$d = 32$
