The gas A₂in the left flask allowed to react with gas B₂present in right flask as, $A_{2} (g) + B_{2} (g) ⇌ 2 AB (g)$ ; K_c= 4 at 27^oC. What is the concentration of AB when equilibrium is established?

Options:

Answer:

Solution:

$K_{c} = \frac{{[AB]}^{2}}{[A_{2}] [B_{2}]}$

$K_{c} = \frac{4 x^{2}}{(2 - x) (4 - x)}$

$\Rightarrow x = \frac{32}{24} = 1.33 mole$

$AB (g) = \frac{2 \times 1 .33}{4} = 0 .66 M$
