Chapter 14, Problem 14.122SP

Interpretation Introduction

(a)

Interpretation:

The rate law from a given reaction needs to be determined.

Concept introduction:

Consider the general reaction

$\text{aA+bB}\to \text{Products}$

Here, A and B are reactants and a, b are stoichiometric coefficients in the balanced chemical reaction. Rate law of the above reaction is as follows:

$\text{Rate}\text{=}k{\left[\text{A}\right]}^m{\left[\text{B}\right]}^n$

Here, k represents rate constant and m, n represents order with respect to A and B.

Interpretation Introduction

(b)

Interpretation:

The mechanism of the given reaction needs to be determined.

Concept introduction:

$\text{aA+bB}\to \text{Products}$

Here, k represents rate constant and m, n represents order with respect to A and B.

Interpretation Introduction

(c)

Interpretation:

The role of C in this mechanism and the reason for it to not appear in the overall reaction needs to be explained.

Concept introduction:

A catalyst is a chemical substance that increases the rate of a reaction, but it remains unchanged. In chemical reactions, catalyst provides substitute pathway or reaction mechanism by lowering activation energy and increasing effective collision of reactants and products.
