MCQ

The figure shows the change in concentration of species $A$ and $B$ as a function of time. The equilibrium constant $K_C$ for the reaction

$2A(g) \rightleftharpoons B(g)$ is

✓
$K_C > 1$
B
$K_C < 1$
C
$K_C = 1$
D
Data insufficient

✓

Answer

Correct option: A.

$K_C > 1$

a
$\mathrm{K}_{\mathrm{c}}=\frac{[\mathrm{B}]}{[\mathrm{A}]^{2}}=\frac{0.4}{(0.1)^{2}}=\frac{0.4}{0.01}=40$
