Chapter 11, Problem 69QRT

(a)

Interpretation Introduction

Interpretation:

‘The balanced equation for the given reaction is the sum of the reaction sequence’- this statement has to be proved.

Concept Introduction:

In a multistep reaction the overall reaction is always the sum of its elementary reactions.  The overall reaction can be found out by adding the entire elementary steps of that particular reaction and cancelling the common terms in the right and left side of the reaction arrow.

(b)

Interpretation Introduction

Interpretation:

The rate determining step has to be identified.

Concept Introduction:

The relationship between rate and initial concentration of reactant is described by rate law.

  $rate=k{\left[concentrationofthereac\tan t\right]}^m$

Where, $k$ is the rate constant and $m$ is the reaction order.

In a multi-step reaction the slowest step will be the rate determining step.
