Abstract
This invention is intended to be used as an Educational demonstration for college level instruction. The invention allows students to visualize the phenomenon of activation energy. Rearrange the unit to demonstrate the SN2 reaction and the potential energy of a covalent bond as a function of internuclear distance. The demonstration can be used as a visual aid to enhance the students understanding of the material presented during the instructors lecture time, or the demonstration can be used directly by the student as a laboratory exercise. The student will gain important graphing skills by using this invention to plot the activation energy curve. The device is made with the most powerful ring magnets commercially available. The size and shape of the ring magnets produces the unusual effects that characterize this invention. An acrylic rod, containing a metric scale for easy measurement, aligns the magnets.
