Dynamic Equilibrium

It is a type of equilibrium that rate forward reaction equals to rate backward reaction. Once the reaction reaches equilibrium, the concentrations of all chemicals remain constant because the chemicals are being comsumed and made at the same rate.

 Condition for dynamic equilibrium
1)    That reaction must be reversible.

2)    It must be in closed system

**Dynamic equilibrium does not need to occur only in chemical reaction. Furthermore,

dissolution can also have dynamic equilibrium occur.
