Areaction mechanism is defined as the sequence of reaction steps that define the pathway from reactants to products. each step in a mechanism is an elementary reaction, which describes a single molecular event of usually one or two molecules interacting. the rate law for an overall reaction is the rate law for the slowest step in the mechanism, which is directly related to the stoichiometric coefficients of the reactants. the exception to this rule occurs when the slowest step contains intermediates. in these cases, the slowest step is usually preceded by an equilibrium step, which can be used to substitute for the intermediates in the overall rate law. part a what is the rate law for the following mechanism in terms of the overall rate constant k? step1: step2: a+bb+c⇌→cd(fast)(slow) express your answer in terms of k and the necessary concentrations (e. g., k*[a]^3*[d]).

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
