Le Chatelier's Principle states that * when a system at equilibrium is disturbed, a new equilibrium constant is established. a disturbing force must be applied to a system in order for it to reach equilibrium when a chemical system is at equilibrium it is no longer possible to alter the system. when a chemical system at equilibrium is disturbed, the system shifts in order to minimize the effect What happens during thermal cracking? * Light oil is subjected to constant pressure and temperature Heavy oil is subjected in high temperature and pressure Introduction of catalyst at lower temperature and pressure Abrupt lighting of combustibles at lower temperature and pressure
