The rate equation shows the detailed dependence of the reaction rate on the concentrations of reactants and other species present. The mathematical forms Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate. Chemical kinetics includes investigations of how experimental conditions influence the speed o The reactions are due to collisions of reactant species. The frequency with which the molecules or ions collide depends upon their concentrations. The more crowded the molecules are, the more likely they are to collide and react with one another. Thus, an increase in the concentrations of the reactants will usually result in the corresponding increase in the reaction rate, while a decrease in the concentrations will usually have a reverse effect. For example, combustion will occur more rapidly in pure oxygen than in air (21% oxygen). The rate equation shows the detailed dependence of the reaction rate on the concentrations of reactants and other species present. The mathematical forms depend on the reaction mechanism. The actual rate equation for a given reaction is determined experimentally and provides information about the reaction mechanism. The mathematical expression of the rate equation is often given by

In this paper Integral method of analysis of data for Batch reactor is used to find the rate and order of reaction of Atenolol epoxide. The integral method is useful for fitting simple chemical reactions. This method puts a particular rate equation to test by integrating and comparing the predicted C versus t curve with experimental C versus t data. If the fit is unsatisfactory, another rate equation is tested. The key raw materials required to produce Atenolol epoxide are Parahydroxyphenylacetamide (PHPA) and Epichlorohydrine (EPH). Firstly, the order and rate with respect to reactant i.e. PHPA is tested and then overall order and rate of equation is evaluated with Integral method of analysis of data. The integrated rate law depends on the kinetics. Since the reaction is being carried out in a batch reactor, the volume of reactor is assumed constant throughout the reaction. The theoretical and actual rates of reaction are then compared for various concentrations of reactant.

In theory, the other reactants could be isolated like bromine was, but the data from bromine can be used to determine the reaction order with regard to them as well. It is found by comparing two reactions where only the concentration of the reactant in question is changed. If p is the reaction order with regard to acetone, \[ p = \dfrac{ \log \dfrac{k_{obsII}}{k_{obsI}}}{ \log u } \nonumber \] The observed rate constant at the higher concentration of acetone is \(k_{obsII}\), while \(k_{obsI}\) is the observed rate constant at the lower concentration of acetone. The ratio of the higher concentration to the lower concentration is given by u. The process is repeated for the hydrogen ion. Mathematical Method The mathematical method is useful when the means to graph are not available. It is essentially determining the slope of the plot that "linearizes the data". This requires plotting concentration versus time data. As in the graphical method, the inverse and natural log of the concentration must be calculated.

While the concepts guiding reaction progress kinetic analysis are not new, the process was formalized by Professor Donna Blackmond (currently at Scripps Research Institute) in the late 1990s and has since seen increasingly widespread use. Unlike more common pseudo-first-order analysis, in which an overwhelming excess of one or more reagents is used relative to a species of interest, RPKA probes reactions at synthetically relevant conditions (i.e. with concentrations and reagent ratios resembling those used in the reaction when not exploring the rate law.) Generally, this analysis involves a system in which the concentrations of multiple reactants are changing measurably over the course of the reaction. As the mechanism can vary depending on the relative and absolute concentrations of the species involved, this approach obtains results that are much more representative of reaction behavior under commonly utilized conditions than do traditional tactics. Furthermore, information obtained by observation of the reaction over time may provide insight…
