What is the difference between dynamic and static equilibrium




















It is also possible for a reaction at equilibrium to respond to external factors by adopting a new point of equilibrium. For example, when extra reactants are added into the system, the rate of the forward reaction increases momentarily until a new balance is reached.

The same applies when the concentration of the products is increased; the rate of the backward reaction will increase until the new point of equilibrium. Furthermore, reactions at equilibrium are also sensitive towards factors such as temperature and pressure. In the case of a static equilibrium, as in a dynamic equilibrium, the number of reactants and the number of products remain the same.

However, the reactions itself has come to a halt without any more reactants converting into products and vice versa. This gives the idea of a static condition as the name implies. For example, imagine that reaction started with several reactant molecules and few product molecules. Dynamic equilibrium is an equilibrium that occurs when a particular chemical system can proceed in both the forward and reverse directions at the same time.

The overall concentration of the chemicals in this system will remain constant at equilibrium providing the conditions temperature, pressure, and composition are not altered. However, this does not mean that the reaction has stopped but continues to form products at exactly the same rate at which the products recombine to form the original chemicals.

Viva Differences. The core difference between static and dynamic equilibrium in chemistry. Read through the comparison chart and watch the comparison video for deeper insight. Static equilibrium is a condition where the reaction occurring in the system has completely stopped. Therefore, there is no movement between reactants and the products corresponding to the chemical reaction.

This is the equation of static equilibrium. If forces acting on a person lie in one line, we can simply add them up. Their upward direction is marked as positive, their downward direction as negative.

In the case of a standing person the reaction force of the ground acts upward on the human body and, in line with our convention, has positive direction.

However, its magnitude is unknown to us. Gravitational force acts downward and therefore has negative direction. If only two forces act on a body in the state of either static or dynamic equilibrium, they have equal magnitude but opposite direction.
