Chapter 15, Problem 15.154MP

Interpretation Introduction

(a)

Interpretation:

The ratio of the dimer to monomers for $\text{0}\text{.100}\text{M}$ acetic acid in benzene needs to be determined.

Concept introduction:

A dimer is an oligomer consisting of two monomers joined by bonds that can be strong or weak, covalent or the intermolecular. The dimer is a compound formed by the union of two radicals or two molecules of the simpler compound.

The reaction is represented as follows:

$n\text{ monomer}\rightleftharpoons \text{dimer}$

Thus, the equilibrium constant can be calculated as follows:

${\text{K}}_{\text{c}}\text{=}\frac{\left[\text{dimer}\right]}{{\left[\text{monomer}\right]}^n}$

Here, n is the number of monomer units.

Interpretation Introduction

(b)

Interpretation:

The ratio of dimers to monomers for $\text{0}\text{.100}\text{M}$ acetic acid in water needs to be determined.

Concept introduction:

A dimer is an oligomer consisting of two monomers joined by bonds that can be strong or weak, covalent or the intermolecular. The dimer is a compound formed by the union of two radicals or two molecules of the simpler compound.

The reaction is represented as follows:

$n\text{ monomer}\rightleftharpoons \text{dimer}$

Thus, the equilibrium constant can be calculated as follows:

${\text{K}}_{\text{c}}\text{=}\frac{\left[\text{dimer}\right]}{{\left[\text{monomer}\right]}^n}$

Here, n is the number of monomer units.

Interpretation Introduction

(c)

Interpretation:

The reason due to which ${\text{K}}_{\text{c}}$ for water solution is much smaller than ${\text{K}}_{\text{c}}$ for the benzene solution needs to be explained.
