Under which of the following conditions can equilibrium not be attained?
Understand the Problem
The question asks about the conditions under which a chemical equilibrium cannot be established. This involves understanding the nature of reversible and irreversible reactions and the requirements for dynamic equilibrium.
Answer
Equilibrium cannot be attained if the concentrations of reactants and products are not constant or if the system is not closed.
Equilibrium cannot be attained if the concentrations of reactants and products are not constant. Also, a system must be closed, meaning no substances can enter or leave the system, for equilibrium to be established.
Answer for screen readers
Equilibrium cannot be attained if the concentrations of reactants and products are not constant. Also, a system must be closed, meaning no substances can enter or leave the system, for equilibrium to be established.
More Information
A system is at equilibrium when the rates of the forward and reverse reactions are equal, and the concentrations of reactants and products are constant.
Tips
A common mistake is thinking all reactions reach equilibrium. Irreversible reactions proceed completely in one direction and do not reach equilibrium.
