Chapter 15, Problem 15.152MP

Interpretation Introduction

(a)

Interpretation:

The value of ${\text{K}}_{\text{p}}$ and ${\text{K}}_{\text{c}}$ at $\text{400K}$ for the given reaction needs to be calculated.

Concept introduction:

For a reversible chemical reaction:

$\text{aA+bB}\rightleftharpoons \text{cC+dD}$

The equilibrium constant is given by the following expression:

${\text{K}}_c\text{=}\frac{{\left[\text{C}\right]}^{\text{c}}\text{.}{\left[\text{D}\right]}^{\text{d}}}{{\left[\text{A}\right]}^{\text{a}}\text{.}{\left[\text{B}\right]}^{\text{b}}}$

Where,

Equilibrium concentration of $\text{A}$ : $\left[\text{A}\right]$

Equilibrium concentration of $\text{B}$ : $\left[\text{B}\right]$

Equilibrium concentration of $\text{C}$ : $\left[\text{C}\right]$

Equilibrium concentration of $\text{D}$ : $\left[\text{D}\right]$

Interpretation Introduction

(b)

Interpretation:

An electron dot structure for ${\text{NO}}_{\text{2}}$ and rationalize the structure of ${\text{N}}_{\text{2}}{\text{O}}_{\text{4}}$ needs to be drawn.

Concept introduction:

An electron dot structure is drawn to represent the arrangement of atoms in a molecule. The total number of electrons are distributed among the atoms to complete their octets.

In the electron dot structures, the lone pair of electrons are represented by dots on the atoms.
