MCQ

$2$ moles of $N_2$ are mixed with $6$ moles of $H_2$ in a closed vessel of one litre capacity. If $50\%\, N_2$ is converted into $NH_3$ till equilibrium, find the value of $K_c$ for the reaction, ${N_2}(g) + 3{H_2}(g) \rightleftharpoons 2N{H_3}(g)$

✓
$4/27$
B
$27/4$
C
$1/27$
D
$27$

✓

Answer

Correct option: A.

$4/27$

a
$\mathop {\mathop {{{\text{N}}_2}}\limits_2 }\limits_{2 - 1} + \mathop {\mathop {3{{\text{H}}_2}}\limits_6 }\limits_{6 - 3} \rightleftharpoons \mathop {\mathop {2{\text{N}}{{\text{H}}_3}}\limits_0 }\limits_2 $

$K_{c}=\frac{2^{2}}{1 \times 3^{3}}=\frac{4}{27}$
