WebIn clock reactions, they contain a complex mixture of chemicals which react in order to cause a physical change after a period of time (Faculty, 2015). The term clock reaction comes from the time taken for a quantity of product to form changes when the concentration of one of the reactants varies, due to different physical changes occurring at different … WebIodine, Cross-disciplinary concepts, Order, Kinetics Abstract The iodine clock reaction can be used to illustrate the kinetic order of a reaction, and an overhead projector demonstration was developed three years ago for general chemistry classes at the University of Notre Dame showing this concept.
