Chapter 6.5, Problem 6.19P

Interpretation Introduction

(a)

Interpretation:

For the reaction, $A+B\underset{}{\rightleftarrows }C+D$ with an equilibrium constant, K = 8, the equilibrium state for the system is to be determined.

Concept Introduction:

For a system to be in equilibrium, both the reactants and products must have the value equal to the equilibrium constant.

If not, then the system is not in equilibrium.

Interpretation Introduction

(b)

Interpretation:

The direction of the reaction is to be found to achieve equilibrium for the following reaction:

  $A+B\underset{}{\overset{}{\rightleftarrows }}C+D$

Concept Introduction:

A system must be in equilibrium to satisfy the reactions. But if a system is not in an equilibrium state, then the system will shift to a certain direction to attain equilibrium.
