Kimberly Redd July 12, 2015 Kinetics Summary Introduction The ability to control that rate of a chemical reaction is an important part of life. For example, it is important that a firework fuse burns long enough for a person to get away, but not too long that the person goes back. The speed at which it burns is controlled by the concentration of potassium nitrate paper on the fuse. Chemical Kinetics is the study of rates at which chemical reactions occur, the factors that affect the speed of reactions, and the mechanisms by which reactions proceed. The reaction rate depends on the concentration of the reactants, the temperature, pressure, and whether a catalyst is involved. This particular experiment studied the kinetics of a reaction between blue dye and NaOCl, or bleach. Reaction progress was monitored spectroscopically using the Spectronic-20 spectrophotometer. Reaction orders were obtained graphically by plotting zero order, first order, and second order plots using data from the Spectronic-20. The order of the reaction can be determined by which plot gives a
