What is dynamic equilibrium of a reaction. Details please if you can. That would really help in my studies

It is when a reaction doesn't move between products and reactants. That is, it achieved chemical equilibrium.

You see, many reactions in nature are reversible meaning that the reactants do not always react, form products and stop. They keep "moving" because the products then transform back into the reactants. And once again the reactants react to form the products again. This repeats itself until the "movement" between products and reactants finally stops. This is called dynamic equilibrium.
