Answer 2

Answer:

For the reaction,

22−2x

2A(g)

+

22−x

B(g)

⇌

03x

3C(g)

+

0x

D

(g)

2 moles each of A and B were taken into a flask. The consumption of A is twice of that of B.

Hence, [A]

<[B]

Also from the reaction stoichiometry,

[A]=−

[B]

or

[B]

The rate of consumption of A is twice the rate of consumption of B.

So the equilibrium concentration of A will be less than the equilibrium concentration of B.

Option B is correct.
