What is the difference between static and dynamic equilibrium?
• In static equilibrium, both microscopic and macroscopic properties remain unchanged whereas, in dynamic equilibrium, the microscopic properties change while the macroscopic properties remain unchanged.
• In mechanics, a system with no unbalanced external forces and external moments can be considered to be in equilibrium. Additionally, if the system is stationary, it is in static equilibrium, and if moving at a constant velocity, it is in dynamic equilibrium.
• In a thermodynamic system, if the temperature is constant and the heat and mass transfer input and output are at equal rates, the system is in (dynamic/ thermodynamic) equilibrium.
• In a chemical system, if the rate of the forward reaction and the backward reaction are the same, the system is said to be in dynamic equilibrium.
