Chapter 17, Problem 37A

Interpretation Introduction

Interpretation:

The equilibrium position is to explained.

Concept introduction

Equilibrium is that stage where rate of forward and rate of reverse reaction becomes equal. Equilibrium position is the position where there is no further tendency to change.

Answer to Problem 37A

When equilibrium is attained, there exists an expression of concentration of the substances involved in equilibrium which becomes constant at a given temperature.

Explanation of Solution

Equilibrium is the state at which the concentrations of reactants and products do not change with time.

At equilibrium , both the forward and the backward reactions are still taking place but the rates of forward and the backward reactions becomes equal. As a result, the concentration of each species becomes constant. Te system is said to be in a dynamic equilibrium.

Rate of forward reaction = rate of backward reaction

Conclusion

When equilibrium is attained, there exists an expression of concentration of the substances involved in equilibrium which becomes constant at a given temperature.
