The initial rate can be found by measuring the gradient of a tangent drawn at t = 0 on a concentration−time graph. A clock reaction is a more convenient way of obtaining the initial rate of a reaction by taking a single measurement.

WebFor this study, I utilized the iodine clock reaction between iodide ion and persulfate ion to determine the order of reaction with respect to iodide ion and persulfate ion and it was found to be 1, which is reported in most literatures.
WebIodine Clock Reaction "Iodine Clock" refers to a group of reactions which involve the mixing of two colorless solutions to produce a ... a, b, and c expected to be integers (0, 1, 2, or 3) or half-integers (1/2, 3/2, 5/2). The reaction is said to have an "overall order" of a + b + c. The initial rate is then related to the initial ...
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.
