IPhO2002 1 I. Determination of e/k B Through Electrolysis Process Background Theory The electrolysis of water is described by the reaction : H 2 O 2H + + O -2 + + 2e - H 2 ; O 2 1 O 2 The reaction takes place when an electric current is supplied through a pair of electrodes immersed in the water. Assume that both gases produced in the reaction are ideal. One of the gases produced by the reaction is kept in a test tube marked by arbitrary scale. By knowing the total charge transferred and the volume of the gas in the test tube the quantity e/k B can be determined, where e is the charge of electron and k B is the Boltzmann constant. For the purpose mentioned above, this experiment is divided into two parts. Part A: Calibration of the arbitrary scale on the test tube by using a dynamic method. This result will be used for part B Part B: Determination of the physical quantity B by means of water electrolysis You are not obliged to carry out the two experiments ( part A and part B ) in alphabetical order The following physical quantities are assumed: Acceleration of gravity, g = (9.78 ± 0.01) ms
