Chapter 6, Problem 64P

Interpretation Introduction

Interpretation:

The direction that reaction to achieve the equilibrium should be determined.

Concept Introduction:

The net concentrations of the reactants and products do not change at equilibrium. They are used to define an expression and the equilibrium constant (K) which has a characteristic value.

For a reaction at a given temperature.

  $\text{K=}\frac{\left[\text{Products}\right]}{\left[\text{reactants}\right]}$

Le Chatelier's principle is a general rule used to explain the effect of a change in reaction conditions on equilibrium.

Le Chatelier's principle states:

If a chemical system at equilibrium is disturbed, equilibrium will shift in the direction to counteract the change.
