WebAboutTranscript. The rate law for a chemical reaction can be determined using the method of initial rates, which involves measuring the initial reaction rate at several different initial … WebWe can measure the rate of reaction (1) by adding a known amount of a standard sodium thiosulfate solution and some starch to the reacting solution. The time required for the solution to turn blue is measured. The rate is given by equation (10). Rate = Moles H 2 O 2 reacted / Time (s) = Moles thiosulfate reacted / Time to turn blue
WebIf the reaction is zero order with respect to A (rate is independent of [A]), then the rate law equation is rate ] dt k (22-4) Integrating the equation, then [A] = -kt + [A] o (22-5) Where [A] o is the initial concentration of reactant A and [A] is the concentration after time period t. Webthe reaction intermediate may be deduced. Rate equation At constant temperature and ionic strength, the rate equation for reaction (R1) is Rate =− (1) d[S2O82−] dt =k [S2O8 2−]m [I−]n In this experiment you will use the initial rate …
