Q 1148112903.     A hypothetical reaction: `A_(g) + B_(g) ⇌ C_(g) + D_(g)` occurs in a single step, the specific rate constant of forward reaction at `T`K is `2.0 × 10^-3 mol^-1 L s^-1`. When start is made with equimolar amounts of `A` and `B`, it is found that the concentration of A is twice that of C at equilibrium. Find the specific rate constant of the backward reaction.
A

`3.0 × 10^-3 mol^-1 Ls^-1`

B

`5.0 × 10^-4 mol^-1 Ls^-1`

C

`2.5 × 10^2 mol^-1 Ls^-1`

D

`8.0 × 10^-3 mol^-1 Ls^-1`
