What are the two types of reactions involved in a reversible chemical reaction?

In a reversible chemical reaction, both a forward reaction and a reverse reaction occur. The forward reaction is the process where reactants are converted into products, while the reverse reaction involves the conversion of products back into reactants. This dynamic equilibrium allows the reaction to proceed in either direction, depending on conditions such as concentration, temperature, and pressure.

Understanding this concept is crucial in the study of chemical equilibria, as it helps explain how systems respond to changes and how the proportions of reactants and products can shift. While other reaction types, such as oxidation and reduction or exothermic and endothermic reactions, describe different chemical processes, they do not capture the reversible nature that is central to the concept presented in this question.
