To solve the problem step by step, we will first find the initial rate of the reaction and then calculate the reaction rate after two minutes.Step 1: Write the Rate Law Expression For a first-order reaction, the rate law can be
The units for the rate of a reaction are mol/L/ s. The units for k are whatever is needed so that substituting into the rate law expression affords the appropriate units for the rate. In this example, the concentration units are mol3/L3. The units for k should be mol-2 L2/s so ...

The general form of the rate expression for methanol carbonylation containing the concentrations of catalyst, promoter, reactants and products was derived from the reaction mechanism containing all the species observed during the reaction and the known chemistry based on the assumption that the oxidative...
This chapter discusses the chemical reaction rate expression and the various variables that influence the reaction rate. Chemical kinetics analyzes the dynamics of chemical reactions. The raw data of chemical kinetics are the measurements of the reactions rates. The equations are used to arrive at an...
The units for a rate constant will vary as appropriate to accommodate the overall order of the reaction. The unit of the rate constant for a zero-order reaction is mol/L·s (or M/s) and that for a first-order reaction is 1/s. The unit of the rate constant for a second-order reac...
