Question

Chapter 7.7, Problem 7.7P

Interpretation Introduction

**Interpretation:**

Effect on equilibrium should be determined after the solution becomes saturated with oxygen.

**Concept Introduction:**

**Chemical equilibrium:**

A chemical equilibrium shifted towards forward direction or backward direction depends on the concentration of both reactant and products.

Consider and equilibrium reaction:

Here, a, b, c and d are coefficient.

If we add excess concentration of c and d, then the chemical equilibrium will shifted in backward direction.
