MCQ
For the reaction $2A_{(g)}  \rightleftharpoons  B_{(g)} + 3C_{(g)}$, at a given temperature $K_c = 16$, what must be the volume of flask. If mixture of $2\, mole$ each of $A, B, C$ exist at equilibrium?
  • A
    $\frac{1}{4}\,L$
  • ✓
    $\frac{1}{2}\,L$
  • C
    $1\,L$
  • D
    None of these
✓

Answer

Correct option: B.
$\frac{1}{2}\,L$
b
                    $2A(g) \rightleftharpoons 3(g) + 2C(g)$

at equation   $2\,mol$      $2\,mol$      $2\,mol$

$\mathrm{K}_{\mathrm{C}}=\frac{2 \times 2^{3}}{2^{2}} \times\left(\frac{1}{\mathrm{V}}\right)^{2}=16$

$\left(\frac{1}{V}\right)^{2}=4 $

$\boxed{V = \frac{1}{2}}$
