Iodine clock order of reaction

Web27 feb. 2014 · Reaction Kinetics: The Iodine Clock Reaction Introduction The “clock reaction” is a reaction famous for its dramatic colorless-to-blue color change, and is often used in chemistry courses to explore the rate at which reactions take place. The color change occurs when I 2 reacts with starch to form a dark blue iodine/starch complex. Web17 aug. 2024 · The iodine clock reaction is a biochemical process used to measure the time it takes for a reaction to occur. The reaction is initiated by the addition of a known amount of iodine to a sample of hydrogen peroxide. The peroxide then decomposes to water and oxygen gas, which is then monitored by a gas detector.

Determination of the Rate Constant for an Iodine Clock Reaction

WebFor this decomposition reaction, we have k = -slope = 0.0006 sec-1. This process can be applied in reverse. If we do not know the order of a given reaction, we can simply plot the data in all three “Linear” forms and see which results in a straight-line. This then gives us the Reaction Order.
