Textbook Problem

A certain reaction has the following general form:

aA bB

At a particular temperature and [A]0 = 2.80 × 10−3 M, concentration versus time data were co11ected for this reaction, and a plot of 1/[A] versus time resulted in a straight line with a slope value of + 3.60 × 10−2 L/mol · s.

a. Determine the rate law, the integrated rate law, and the value of the rate constant for this reaction.

b. Calculate the half-life for this reaction.

c. How much time is required for the concentration of A to decrease to 7.00 × 10−4 M?

(a)

Interpretation Introduction

Interpretation: The general reaction is given. The initial concentration and slope value of 1/[A] versus time graph is given. Based on these data answers are to be given.

Concept introduction: The change observed in the concentration of a reactant or a product per unit time is known as the rate of the particular reaction. The differential rate law provides the rate of a reaction at specific reaction concentrations.

To determine: The rate law, the integrated rate law and the value of rate constant for the given reaction.

Explanation

To determine: The rate law for the given reaction.

Given

The initial concentration is 2.80×103M .

The value of slope is 3.60×102 .

The given general equation is,

aAbB

The rate law gives the relation between reaction rate and concentration of reactants. The rate law is represented as,

Rate=k[A]a

Where,

  • k is rate constant.
  • [A] is concentration of reactant.
  • a is reaction order.

To determine: The integrated rate law for the given reaction.

Given

The initial concentration of A is 2.80×103M .

The given general equation is,

aAbB

The rate law in integral form is known as integrated rate law. It gives the relation between concentration of reactant or product with time
