A follows parallel path first order reaction to give B and C as given below (Take antilog (0.156)=1.428)

The concentratio of A after 5 hours is

A

`3.6xxx10^(-2)M`

B

`6xx10^(-2)M`

C

`1.5xx10^(-2)M`

D

`1.39xx10^(-1)M`

Text Solution

Verified by Experts

The correct Answer is:
D
Assume that it is 1st order and find `C_(t)=?Kxxt=2.303xxlog((C_(0))/(C_(t))),Ct=0.139M`
