The purpose of this demonstration is to investigate the effect of sodium thiosulfate concentration on the rate of reaction of sodium thiosulfate with hydrochloric acid. The reaction, which produces solid sulfur, will be followed by measuring the time needed for the reaction mixture to become opaque.

Chemical kinetics deals with the speed, or rate, of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that react in a second. Rates of Chemical Reactions II lab report. The rate and order of reaction for the decomposition of hydrogen peroxide was determined to a reasonable rate of success. Furthermore, laboratory experience and practice with using universal formulas were gained. atbry Instructor REPORT SHEET EXPERIMENT Rates of 30 Chemical Reactions II: | Rate and Order Rates of Chemical Reactions II: Rate and Order.
