2002 U.S. National Chemistry Olympiad National Exam - Part III

Two laboratory problems are put forth for chemistry students. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a potato and decomposition rate of hydrogen peroxide. The second requires that they determine the equilibrium constant for a reaction involving urea. All of these National Chemistry Olympiad exams are tremendous resources to use in your classroom as lab investigations or practical exams.
