When there are two reactants and they react to give products, then it is forward reactions

If the products themselves react to give back the same reactants then it is backward reaction

there are two types of reactions: reversible and irreversible. in that, in reversible reaction, the reactants can give products and the products react back to give the original rectants. the process in which the reactants give product is called forward reaction and the reaction in which we obtain the reactants back from their products is called reverse reaction. best luck for exams... ipsa...

In a chemical reaction, chemical equilibrium is the state in which the concentrations of the reactants and products have not yet changed with time. It occurs only in reversible reactions, and not in irreversible reactions. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and reverse reactions are generally not zero but, being equal, there are no net changes in the concentrations of the reactant and product. This process is called dynamic equilibrium.
