Rev: 201 6 - 201 7 4 -1 experiment 4: kinetics of an iodine clock reaction i introduction this experiment is designed to study the kinetics of a chemical reaction. Therefore the reaction is zero order for iodine and it also zero order for bromine in the similar bromination reaction this suggests there is a slow rate determining step involving the ketone and the hydrogen ion in the mechanism and what ever happens next eg involving the iodine, is much faster. Reaction kinetics for the iodination of acetone, a color changing reaction, in the presence of an acid catalyst were studied using spectrophotometer constructed in the lab these results were equivalent to what may be recorded using a commercial spectrophotometer the purpose of this experiment is.

Experiment a1: kinetics of the reaction between acetone and iodine the key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of. This reaction is quite slow, making its rate ideal to measure in a lab setting it is also convenient to study because molecular iodine, i 2, is easy to detect i 2 reacts with starch to form a deeply blue-colored complex by adding starch to the reaction mixtures, a deep blue color is observed as soon as iodine is produced by the reaction.
