[O2] quadrupled, [NO] halved The initial rate of the above reaction remains the same, if the temperature is raised from 460°C to 600°C, and the initial concentrations are halved. 7.2. Calculate the activation energy of the reaction. B. The iodation of acetone Measuring the rate of a chemical reaction and its dependence on several parameters (concentration of involved species, temperature, pressure, and catalysts) enables the chemist to draw conclusions about the reaction mechanism and thus about the detailed way of the reaction. In compulsory lab lessons at a Viennese High School the iodation of acetone under acid catalysis is investigated: The reaction does not proceed in one step, but in several ones, one of them being the rate determining step (RDS). The rate equation of the reaction is given: The students have to mix various volumes of the involved reaction partners, knowing initial concentrations. Additionally they have to measure the time until the colour of iodine disappears, therefore = .
