Q. Give the hypothetical reaction mechanism $A\overset{\ \ \ I\ \ \ \ \ \ \ }{\rightarrow}B\overset{\ \ \ II\ \ \ \ \ \ \ }{\rightarrow}C\overset{\ \ \ III\ \ \ \ \ \ \ }{\rightarrow}D\overset{\ \ IV\ \ \ \ \ \ \ }{\rightarrow}E$ and the date as [table] Species formed | Rate of its Formation ; B | 0.002 mol/h, per mole of A ; C | 0.030 mol/h, per mole of B ; D | 0.011 mol/h, per mole of C ; E | 0.420 mol/h, per mole of D [/table] The rate determining step is
A) Step I
B) Step II
C) Step III
D) Step IV
Explanation
(a)
The slowest step is the rate determining step. Formation of B(i.e., step I) is the slowest step, therefore step I is the rate determining step.
