Chapter 14: Problem 8

Give one example of a stress on a reaction in aqueous solution and at equilibrium.

Short Answer

Expert verified
An example of stress on a reaction at equilibrium in an aqueous solution could be adding more of a reactant to the solution. According to Le Chatelier's Principle, the system will counter this change by shifting the equilibrium towards the products to consume the excess reactants, thus re-establishing the equilibrium.

Step by step solution

01

Understanding equilibrium in chemical reactions

In the context of chemical reactions, equilibrium refers to the state in which both reactants and products are present in concentrations which have no further tendency to change with time. This doesn't necessarily mean that the amount of reactants and products will be equal, but that their rates of reaction will be the same, hence, no net change would be observed.
02

Understanding stress in terms of Le Chatelier's Principle

According to Le Chatelier's Principle, if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium will shift to counteract the change to re-establish an equilibrium. This change in conditions is often referred to as 'stress' on the reaction.
03

Provide an example for the stress on a reaction

An example of stress could be an increase in the concentration of reactants in a given solution. According to Le Chatelier's Principle, the system will respond to this change to re-establish equilibrium. In this case, the equilibrium will shift towards the products to consume the excess reactants, hence re-establishing equilibrium.
