Passage: A reaction can be symbolically depicted through a chemical equation. While in a non-nuclear chemical reaction the number and kind of atoms on both sides of the equation are equal, for a nuclear reaction this holds true only for the nuclear particles viz. protons and neutrons.The sequence of steps in which the reorganization of chemical bonds may be taking place in the course of a chemical reaction is called its mechanism. A chemical reaction can be envisioned to take place in a number of steps, each of which may have a different speed. Many reaction intermediates with stability variable can thus be envisaged during the course of a reaction. Reaction mechanisms are proposed to explain the kinetics and the relative mix of a reaction. Wengi wa wanakemia wa kimwili ni maalumu katika kuchunguza na kupendekeza mifumo mbalimbali ya atomu za kemikali. Sheria kadhaa kama vile Woodman na Howard, wakati wa kupendekeza mara nyingi huja kwa aina gani ya utaratibu wa athari ya kemikali.
