Solution

The correct option is C 0.66 M
The reaction is,

$\begin{matrix} A_{2} (g) & + & B_{2} (g) & ⇌ & 2 A B (g) M o l e s a t e q m & 2 - x & 4 - x & 2 x \end{matrix}$

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

putting values, we get;
$\Rightarrow x = \frac{32}{24} = 1.33 m o l e$

Here total volume= $1 l + 3 l = 4 l$
Concentration of AB= $\frac{2 x}{v o l u m e}$
= $\frac{2 x}{4}$
Putting the values,
Concentration of AB = $0.66 M$

2mol of A2 gas in one flask (1 lit volume) is allowed to react with 4 mol of B2 gas presence in another flask (3 lit volume) as A2 (g)+B2 (g)⇌2AB (g);Kc=4 at 27oC. What is the concentration of AB when equilibrium is established?

The correct option is C 0.66 M The reaction is, A2(g)+B2(g)⇌2AB(g)Moles at eqm2−x4−x2x Kc=4x2(2−x)(4−x) putting values, we get; ⇒x=3224=1.33 mole Here total volume=1l+3l=4l Concentration of AB=2xvolume =2x4 Putting the values, Concentration of AB = 0.66 M
