For the overall reaction between A and B...

For the overall reaction between A and B to yield C and D, two mechanisms are proposed:
I. `A+BtoAB*toC+D,k_(1)=1xx10^(-5)M^(-1)s^(-1)`
II. `AtoA"*"toE,k_(1)=1xx10^(-4)s^(-1)`,
`E+BtoC+d,k_(2)=1xx10^(10)M^(-1)s^(-1)`
(species with * are short lived)
Rate of reaction for mechanism I when concentration of each is 0.1 M, is

A

`1xx10^(-7)Ms^(-1)`

B

`1xx10^(-6)Ms^(-1)`

C

`1xx10^(-5)Ms^(-1)`

D

`1xx10^(-4)Ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`r_(1)=K_(1)^(1)[A]^(1)[B]^(1)=1xx10^(-5)xx(0.1)^(1)xx(0.1)^(1)=1xx10^(-7)`
