Rate of the given reaction,
(1) `A + B overset(r_(1)=0.05) to X`
(2) `X + B overset(r_(2)=0.89) to Y`
(3) `Y + A overset(r_(3)=0.001) to AY`
(4) `AY + B overset(r_(4)=0.10) to AYB` will be determined by

Options

A. Step (i) Because the reaction starts with the formation of X
B. Step (ii) because it is fastest step
C. Step (iii) because it is the slowest step
D. Step (iv) because it ends the reaction

Answer

C

Explanation

Slowest step is the rate determining step .
