WebJan 17, 2024 · In fact, problems often are formatted along the lines of, "The mechanism for a reaction is {mechanism}. If {rate law} is the experimentally determined rate law, is this mechanism valid?" Since the overall rate law of a reaction must be found experimentally, it can be used to verify mechanisms. Example Free-Response Question WebPractice Problems: Integrated Rate Laws Describe how graphical methods can be used to determine the order of a reaction and its rate constant from a series of data that includes the concentration of A at varying times. Solution:
WebFeb 13, 2024 · $\begingroup$ Just because the rate law matches the stoichiometry does not mean it is an elementary reaction. Lots of multi-step mechanisms would result in the same rate law. On the other hand, if you specify that a reaction is an elementary one, you can infer the rate law from the coefficients of the reaction as written. $\endgroup$ – WebREACTION MECHANISMS (practice problems) For the following reactions and their proposed mechanisms: − derive the rate law − denote reaction intermediate(s) − denote …
