What Is Dynamic Equilibrium?

The video tutorial explains dynamic equilibrium using a digging analogy, where two processes occur at the same rate, resulting in no observable change. It outlines the criteria for equilibrium: a reversible process in a closed system. An example of hydrogen and iodine reacting to form hydrogen iodide is provided, illustrating how equilibrium is achieved when forward and reverse reactions occur at the same rate. The video also covers phase change equilibrium using bromine as an example. In summary, equilibrium is when the forward and reverse reaction rates are equal, with no observable changes.

Explain the concept of dynamic equilibrium in the context of a reversible reaction.
