Chapter 12, Problem 12.97SP

(a)

Interpretation Introduction

Interpretation:

The balanced equation for the given overall reaction has to be given.

Concept introduction:

In a balanced equation the number of atoms of each element as a reactant is equal to the number of atoms of that element as a product.

Coefficient is a number placed before a formula in a chemical equation.

A balanced equation should be obeying the law of conservation of mass. Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a chemical reaction atoms are neither be created nor be destroyed”.

(b)

Interpretation Introduction

Interpretation:

The intermediates in the given reaction have to be identified.

Concept introduction:

Intermediate: Intermediate is a short lived molecule of a particular reaction which is formed from reactant molecules and then reacts further to form products. These molecule entities are not found in the overall reaction.

(c)

Interpretation Introduction

Interpretation:

Given mechanism is whether is consistent or not with the experimental rate law has to be shown.

Concept introduction:

Rate of reaction: The rate of a reaction is defined by the change in concentration of substrate (reactant) or target (product) with change in time.

$\text{Rate}\text{=}\frac{\text{Concentration}\text{change}\left(\text{in}\text{reactant}\text{or}\text{product}\right)}{\text{Time}\text{change}}$

The rate law for the slowest step in a reaction mechanism (rate determining step) is the rate law for overall reaction.

Rate law: It is an equation that related to the dependence of the reaction rate on the concentration of each substrate (reactants).

Rate constant: Rate constant is an expression used to relate the rate of a reaction to the concentration of reactants participating in the reaction.

(d)

Interpretation Introduction

Interpretation:

The rate constant $\text{k}$ has to be related to the rate constants of the elementary reactions.

Concept introduction:

Rate of reaction: The rate of a reaction is defined by the change in concentration of substrate (reactant) or target (product) with change in time.

$\text{Rate}\text{=}\frac{\text{Concentration}\text{change}\left(\text{in}\text{reactant}\text{or}\text{product}\right)}{\text{Time}\text{change}}$

Rate law: It is an equation that related to the dependence of the reaction rate on the concentration of each substrate (reactants).

Rate constant: Rate constant is an expression used to relate the rate of a reaction to the concentration of reactants participating in the reaction.
