Chemical reaction is the process by which one or more substances are converted into different substance or substances.
The substances which undergo chemical reaction are called as reactants while the substances which are produced by the reaction are called as products. During chemical reaction, chemical bonds of substrates undergo breaking and formation process to form an entire new product which may have same or different physical and chemical properties as compared to substrates.
Energy is either used or released during the chemical reaction. When the energy is used, it is termed as endothermic reaction but when the energy is produced by the reaction, it is termed as exothermic reaction.
Lastly, gases may or may not participate in a chemical reaction.
