Chapter 15, Problem 15.161MP

Interpretation Introduction

(a)

Interpretation:

Thevaluesof equilibrium concentrations of monomer and dimer needs to be determined.

Concept introduction:

A general equilibrium reaction can be written as follows:

$aA+bB\rightleftharpoons cC+dD$

For a general reaction, the expression for K_c can be represented as follows:

$K_c=\frac{{\left[C\right]}^c{\left[D\right]}^d}{{\left[A\right]}^a{\left[B\right]}^b}$

It can also be written in the form of partial pressure of all the gases as follows:

$K_p=\frac{{\left(P_C\right)}^c{\left(P_D\right)}^d}{{\left(P_A\right)}^a{\left(P_B\right)}^b}$

Interpretation Introduction

(b)

Interpretation:

The osmotic pressure of the solution needs to be determined.

Concept introduction:

The osmotic pressure can be calculated as follows:

$\Pi =cRT$

Here, c is concentration/molarity of the solution, R is Universal gas constant and T is temperature.
