Determination of a rate law lab

WebUpon completion of this lab, the student will be able to: 1) Measure the rate of a chemical reaction and determine the rate law. 2) Evaluate the effect of temperature on the rate of a chemical reaction and determine the activation energy. 3) Assess the role of a catalyst on the rate of a chemical reaction. Introduction WebThe rate law for this reaction is in the form: rate = k [CV +] m [OH –] n, where k is the rate constant for the reaction, m is the order with respect to crystal violet (CV + ), and n is the order with respect to the hydroxide ion.
