What is equilibrium. Chemical equilibrium and ionic equilibrium difference

Equilibrium

• Equilibrium is the state of a process in which the properties like temperature, pressure, and concentration etc of the system do not show any change with passage of time.

• In all processes which attain equilibrium, two opposing processes are involved.

• Equilibrium is attained when the rates of the two opposing processes become equal. 

• If the opposing processes involve only physical changes, the equilibrium is called Physical Equilibrium. 

• If the opposing processes are chemical reactions, the equilibrium is called Chemical Equilibrium.
