·      Chemical Reaction is a process by which one or more substances get transferred into new substances

·      The substance which get transformed or which under go chemical reaction is called reactants

·      The new substance formed as a result of chemical reaction is called products

·      A reaction is which heat is evolved is called the exothermic reaction

·      A reaction in which heat is absorbed is called endothermic reaction.

·      A chemical reaction in which reactant react to produce product and the product in turn react with one another to produce the reactant is called reversible reaction.

·      The chemical reaction in which reactant react to produce product and the products does not reversibly produce reactant are called irreversible reaction.

·      Chemical reaction in which light energy is either absorbed or released is called photochemical reaction

·      Chemical reaction in which electric energy is either absorbed or released is called electrochemical reactions.
