Answer:
A chemical reaction is referred to as the process in which a set of chemical substances tend to react with one another, which, as a result, leads to their conversion from one form into several other different forms. The initial substances that are used the reaction are together known as reactants, whereas the final substances that get formed after the reaction has taken place are referred to as products. The chemical properties, in general, of both the reactants and the products, tend to differ from each other. Depending on whether the reaction gets initiated in the presence of energy or without the energy, it is divided into two different types, which is the spontaneous reaction which occurs on its own and the non-spontaneous reaction which needs energy to activate its process.
