A+Bleftharpoons3C t=0124=(1/3)(2/3)(4/3)KC=10 QC=([. C ].3/[. A ]. [. B ].) =(((4/3))3/((1)3) ((2)3) =(64 × 9/27 × 2)=(64/6)=10.6 boxed/Qc > Kc) Backward direction

Q. For the reaction; $A + B ⇌ 3 C$ , at $2 5^{\circ} C$ , a $3$ litre vessel contains $1, 2, 4$ moles of $A, B$ and $C$ respectively. If $K_{c}$ , for the reaction is $10$ , the reaction will proceed in:

Forward direction

Backward direction

In either direction

In equilibrium

$A + B ⇌ 3 C$
$t = 0124 = \frac{1}{3} \frac{2}{3} \frac{4}{3} K_{C} = 10$
$Q_{C} = \frac{[ C ] ^{3}}{[ A ] [ B ]}$
$= \frac{( \frac{4}{3} ) ^{3}}{( \frac{1}{3} ) ( \frac{2}{3} )}$
$= \frac{64 \times 9}{27 \times 2} = \frac{64}{6} = 10.6$
$Q_{c} > K_{c}$
Backward direction
