Chapter 15, Problem 15.159MP

Interpretation Introduction

(a)

Interpretation:

The number of gaseous naphthalene molecules 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 number of moth balls required to saturate the room with gaseous naphthalene needs to be determined.

Concept introduction:

The volume of sphere is calculated as follows:

$V=\frac{4}{3}\pi r^3$

Here, r is radius of the sphere.
