Chapter 13.3, Problem 21PP

(a)

Interpretation Introduction

Interpretation: Whether the following equilibrium is homogenous or heterogeneous equilibrium should be determined:

  ${\text{2O}}_{\text{3}}\text{(g)}\rightleftarrows {\text{3O}}_{\text{2}}\text{(g)}$

Concept Introduction:

Reactions in which all the products and reactants are in the same phase in the equilibrium conditions is said to be homogenous equilibria whereas reactions in which all the products and reactants are present in more than one phase in the equilibrium conditions is said to be heterogeneous equilibria.

(b)

Interpretation Introduction

Interpretation: Whether the following equilibrium is homogenous or heterogeneous equilibrium should be determined:

  ${\text{2NaHCO}}_{\text{3}}\text{(s)}\rightleftarrows {\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}\text{(s)}\text{+}{\text{CO}}_{\text{2}}\text{(g)}\text{+}{\text{H}}_{\text{2}}\text{O(g)}$

Concept Introduction:

Reactions in which all the products and reactants are in the same phase in the equilibrium conditions is said to be homogenous equilibria whereas reactions in which all the products and reactants are present in more than one phase in the equilibrium conditions is said to be heterogeneous equilibria.

(c)

Interpretation Introduction

Interpretation: Whether the following equilibrium is homogenous or heterogeneous equilibrium should be determined:

  ${\text{C}}_{\text{6}}{\text{H}}_{\text{6}}\text{(g)}\text{+}{\text{3H}}_{\text{2}}\text{(g)}\rightleftarrows {\text{C}}_{\text{6}}{\text{H}}_{\text{12}}\text{(g)}$

Concept Introduction:

Reactions in which all the products and reactants are in the same phase in the equilibrium conditions is said to be homogenous equilibria whereas reactions in which all the products and reactants are present in more than one phase in the equilibrium conditions is said to be heterogeneous equilibria.

(d)

Interpretation Introduction

Interpretation: Whether the following equilibrium is homogenous or heterogeneous equilibrium should be determined:

  $\text{4HCl(g)}\text{+}\text{Si(s)}\rightleftarrows {\text{SiCl}}_{\text{4}}\text{(l)}\text{+}{\text{2H}}_{\text{2}}\text{(g)}$

Concept Introduction:

Reactions in which all the products and reactants are in the same phase in the equilibrium conditions is said to be homogenous equilibria whereas reactions in which all the products and reactants are present in more than one phase in the equilibrium conditions is said to be heterogeneous equilibria.
