Solution

The correct option is B $2.4$
According to the given chemical equation, on consumption of one mol each of 'A' and 'B' produces '2' mol of 'C'
thus,
$A + B ⇋ 2 C$
$t = o, 230$
$t = t_{e q} 2 - x 3 - x 2 x$

Now, according to formula,
$K = \frac{[C]^{2}}{[A] [B]} \Rightarrow 4 = \frac{(2 x)^{2}}{(2 - x) (3 - x)}$

On, simplification we get
x = 1.2, hence $2 x = 2 \times 1.2 = 2.4$
