`2mol` each of `A` and `B` are taken in a container to carry out the following reaction:
`2A(g)+B(g)hArr2C(g)+2D(g)`
When the system attains equilibrium, we have

A

`[A]lt[B]`

B

`[A]gt[B]`

C

`[A]=[B]`

D

`[A]=[B]=[C]=[D]`

Text Solution

Verified by Experts

The correct Answer is:
A
According to the stoichiometry of the reaction, for `1 mol` of `B` consumed, `2 mol` of `A` are converted into products. Thus, at equilibrium, the concentration of `A` will be less than that of B as we start with equal concentrations of `A` and `B`.
