R. China This study provides a strategy for controlling the kinetics of formic acid oxidation by potassium bromide. This strategy resolves the nonlinear deviation of the plot of electromotive force against time and ensures that formic acid oxidation follows first-order kinetics over a wide range of reaction temperatures. The methodology reported here should help instructors optimize their teaching efficiency and provides students with valuable insight into the control of chemical kinetics. http://pubs.sciepub.com/wjce/6/3/5/wjce-6-3-5.pdf controlling kinetics of the formic acid oxidation potassium bromide
