Chapter 22, Problem 22.77P

(a)

Interpretation Introduction

Interpretation:

The balanced equation for given reaction has to be written.

(b)

Interpretation Introduction

Interpretation:

The value of K less than or greater than one has to be determined.

Concept Introduction:

Equilibrium constant: at equilibrium the ratio of products to reactants (each raised to the power corresponding to its stoichiometric coefficient) has a constant value, K.

For a general reaction, $\text{aA+bB }\underset{}{\overset{}{\rightleftharpoons }}\text{ cC+dD}$

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

(c)

Interpretation Introduction

Interpretation:

The equilibrium constant K for the given reaction has to be determined.

Concept Introduction:

Equilibrium constant: at equilibrium the ratio of products to reactants (each raised to the power corresponding to its stoichiometric coefficient) has a constant value, K.

For a general reaction, $\text{aA+bB }\underset{}{\overset{}{\rightleftharpoons }}\text{ cC+dD}$

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