Two first order reaction hasve halflives...

Two first order reaction hasve halflives in 1:2 ratio. After two halflives of first reaction. What is the ratio of their rates of reactions?(Initial concentrations same)

A

`1:2`

B

`1:3`

C

`1:4`

D

`1:1`

Text Solution

Verified by Experts

The correct Answer is:
D
`r=K.C,(r_(1))/(r_(2))=(0.693/(1x)xx(C_(1))/4)/(0.693/(2x)xx(C_(1))/2)implies1:1`
