### Definition of equilibrium

Could I have a clarification on what it means exactly when a reaction reaches equilibrium? Thank you

### Re: Definition of equilibrium

The concentration of both reactants and products do not change.

### Re: Definition of equilibrium

A reaction has reached equilibrium when the concentration of reactants and products no longer changes. Reactions are still occurring, but the rate at which reactants become products is equal to the rate at which products become reactants. For example in the reaction $A\leftrightharpoons B$, equilibrium has been reached when the rate at which A-->B is equal to the rate at which B-->A, and the concentrations of A and B don't change.

### Re: Definition of equilibrium

In addition to this, a system reaches equilibrium when the forward and reverse reaction rates are equal.

### Re: Definition of equilibrium

When a reaction reaches equilibrium, the forward and reverse reactions continue to proceed while the concentrations of reactants and products do not change.
