Overhead Projector Demonstrations
A New Twist on the Iodine Clock Reaction: Determining the Order of a Reaction

Abstract
The Landolt iodine clock reaction is a reliable and well-used chemistry demonstration owing to a variety of features: ease of solution preparation, striking color change indicating reaction completion, convenience in changing reaction "clock time", and effective dramatic presentation. The iodine clock reaction can also 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. This demonstration has been used successfully with consistent results since that time.
