Reaction for first order decay of A is given as:

Where `k_(1) & k_(2)` are rate constnat and related as, `k_(1): k_(2) =1:2.` Find concentration of C at `oo` time if it starts with 2M of initial concentration of A.

A

2/3 M

B

4/3 M

C

1/6 M

D

1/4 M

Text Solution

Verified by Experts

The correct Answer is:
A
`[C] = (K _(1)[A])/(k _(1)+ k _(2)) (1-e ^((k _(2)+ k _(2)t )))`
`[C]_(oo) = (K_(1))/(k_(1) + k _(2)) xx2 = 2/3 M.`
