(a)
Interpretation:
Rate law for the given reaction has to be determined.
Concept introduction:
Rate of the reaction is the change in the concentration of reactant or a product with time.
The rate law expresses the relationship of the rate of a reaction to the rate constant.
Rate equation for the general reaction
(a)

Answer to Problem 13.136QP
Rate law for the given reaction is,
Explanation of Solution
The given reaction is,
The rate law expresses the relationship of the rate of a reaction to the rate constant.
Rate equation for the general reaction
Similarly, rate law for the given reaction can be written as folllows,
(b)
Interpretation:
Check whether it is possible to simplify the rate law for the given reaction under the given conditions if so, the simplified rate law for this reaction has to be written.
Concept introduction:
Rate of the reaction is the change in the concentration of reactant or a product with time.
Rate equation for the general reaction
Order of a reaction: The sum of exponents of the concentrations in the rate law for the reaction is said to be order of a reaction.
When a reactant is made much more concentrated than the other, it is made to have no effect on the rate of that particular reaction. Such type of reaction is considered as pseudo (fake) order reaction.
(b)

Answer to Problem 13.136QP
The simplified rate law for the given reaction is,
Explanation of Solution
The given reaction is,
Rate law for the given reaction can be written as folllows,
Order of this reaction is
Therefore the rate law can be simplyfied, and it is,
(c)
Interpretation:
Under the given condition half-life of the reaction has to be determined.
Concept introduction:
Rate of the reaction is the change in the concentration of reactant or a product with time.
Rate equation for the general reaction
Order of a reaction: The sum of exponents of the concentrations in the rate law for the reaction is said to be order of a reaction.
When a reactant is made much more concentrated than the other, it is made to have no effect on the rate of that particular reaction. Such type of reaction is considered as pseudo (fake) order reaction.
Half-life is the time required for one half of a reactant to react.
For a second order reaction,
(c)

Explanation of Solution
The given reaction is,
Reaction follows pseudo-fist order kinetics,
Therefore the rate law can be simplyfied, and it is,
Herein a sample of air at a certain temperture is contaminated with
If the concentration of
