WebNotice. This record has been edited as far as possible, missing data will be added when the version of record is issued. WebIntroduction: The iodine clock reaction is particularly well-suited as an introduction to reaction rates and kinetics. In 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).
