Question -

At a certain temperature and a total pressure of $10_{5}$ Pa, iodine vapours contain $40 %$ by volume of iodine atoms
$[I_{2} (g) ⇋ 2 I (g)] . K_{p}$ for the equilibrium will be

Options:

A .

0.67

B .

1.5

C .

2.67 \times 10^{4}

D .

9.0 \times 10^{4}

Answer: Option C
:
C
Partial pressure of I atoms

(p_{l}) = 40 \times 10^{5} / 100 P a = 0.4 \times 10^{5} P a

Partial pressure of

l_{2} (p_{2}) = 60 \times 10^{5} / 100 P a = 0.6 \times 10^{5} P a

K_{p} = (p_{1})^{2} / p_{2} = (0.4 \times 10^{5})^{2} / (0.6 \times 10^{5}) = 2.67 \times 10^{4}
