What is a chemical reaction?

A chemical reaction refers to the process in which one or more substances are transformed into new substances with different chemical properties. It involves the breaking and formation of chemical bonds between atoms, resulting in the rearrangement of atoms to create different molecules or compounds. Chemical reactions are characterized by the input of energy, known as the activation energy, as well as the release or absorption of energy, often in the form of heat, light, or sound. These reactions occur when reactant molecules collide with sufficient energy and in the correct orientation, leading to the formation of products and the conservation of mass and energy. Chemical reactions are fundamental to countless natural and synthetic processes, from photosynthesis and digestion to combustion and the production of materials.
