Fig. 2: This is an indirect graph showing the various data collected. The period and temperature are corresponding. The equation in the graph shows the data fit into the Arhenius equation. Cooler temperatures increase the oscillation period. The Briggs – Rauscher reaction has an activation energy of approximately 160 joules per mole.
