Dynamic Equilibrium:
The state of a reversible reaction carried out in a closed container where the rates of forward and backward reactions are equal and constant.

A reversible reaction appears to stop when no overall change is taking place; the reaction is said to be in equilibrium.
For example, a reaction may come to be in equilibrium when 75% of the reactants have changed into products. Under these conditions, the composition of the equilibrium mixture is 75% products and 25% reactants, and this composition is known as the position of equilibrium.

At equilibrium, there is no overall change from reactants to products and it seems as though the reaction has stopped. This is not actually the case. There is no reason why the forward reaction, that is, the reaction between the reactants, should not continue, since there are still reactants present in the mixture, The reason why there is no overall change is that the back reaction, which tums the products back into reactants, is now going at exactly the same rate. A reversible reaction in which the forward and back reactions are both taking place at the same rate is termed a dynamic equilibrium.

An example of a dynamic equilibrium in the gas phase is the reaction of nitrogen and hydrogen to form ammonia in the Haber process:
N2(g) + 3H2(g) → 2NH3(g)

Dynamic equilibria can also take place in the liquid phase:
2H+(aq) + 2CrO4 2-(aq) → Cr2O7 2-(aq) + H2O(l)

In a dynamic equilibrium:
● the forward reaction takes place at the same rate as the reverse reaction
● there is no net change in the concentration of each substance
● the equilibrium compositions of the substances can be approached from either reactants or products

This is super helpful for p1.
I love how you've compiled questions for every topic which makes it so much easier to practice for my p1 exam tomorrow. Please keep making such videos on topicals 🤌🏻🤌🏻
