Question

For the reaction $2A\left(g\right)\rightleftharpoons B\left(g\right)+3C\left(g\right)$, at a given temperature, $K_c=16$. What must be the volume of the flask, if a mixture of $2mole$ each of $A,B$ and $C$ exist in equilibrium ?

• A. $\frac{1}{4}$
• B. $\frac{1}{2}$
• C. $1$
• D. $Noneofthese$

Answer 1

The correct option is B $\frac{1}{2}$

$K_c=\frac{n_g{n}_c^3}{n_A^2}\times \frac{1}{V^2}$
$\Rightarrow 16=\frac{2\times 2^3}{2^2\times V^2}$
$\Rightarrow V=\frac{1}{2}$
