Chapter 17, Problem 52A

Interpretation Introduction

Interpretation:

The way the equilibrium shifts to left due to a stress caused by removing a reactant is to be explained.

Concept introduction:

According to Le Chatelier’s principle, when concentration of the reactants and products are changed, equilibrium position is also changes. As lowering the temperature, the equilibrium is also shifts towards the right side or product side and more products are formed. So, there is a stress on equilibrium by increasing or decreasing of the concentration of reactants and products.

Answer to Problem 52A

As lowering the temperature, the equilibrium is also shifts towards the right side or product side and more products are formed and vice versa. So, there is a stress on equilibrium by increasing or decreasing of the concentration of reactants and products.

When some reactants is removes, equilibrium is disturbed as rate of formation decreases. So the stress relieved by converting products to reactants and equilibrium shifts to left.

Explanation of Solution

According to Le Chatelier’s principle, by changing the temperature the equilibrium position is also changes. As temperature is decreases the equilibrium is shifts towards the right side or product side and vice versa. Changing the temperature favors one reaction over the other. On the other hand, at constant temperature the equilibrium is not affected.

As lowering the temperature the equilibrium is also shifts towards the right side or product side and more products are formed and vice versa. So, there is a stress on equilibrium by increasing or decreasing of the concentration of reactants and products.

When some reactants is remove then equilibrium is disturbed as rate of formation decreases. So, the stress relieved by converting products to reactants and equilibrium shifts to left. In this way, according to Le Chatelier’s principle, the equilibrium shifts to left by removing the reactants to attains the equilibrium quickly.

Conclusion

As lowering the temperature the equilibrium is also shifts towards the right side or product side and more products are formed and vice versa. So, there is a stress on equilibrium by increasing or decreasing of the concentration of reactants and products.

When some reactants is remove then equilibrium is disturbed as rate of formation decreases. So the stress relieved by converting products to reactants and equilibrium shifts to left.
