A study into the kinetics of a chemical reaction is usually carried out with one or both of two main goals in mind 1Analysis of the sequence of elementary steps giving rise to the overall reactionDetermination of the absolute rate of the reaction andor its individual elementary steps.
Chemical kinetics is the study of the rates of chemical reactions if changes in conditions impact the speed of a reaction we can better understand what caused the reactionIn this course you’ll learn to understand complicated data sets and analysis techniques for measuring and understanding these rate changes.
Chemical reaction kinetics provide a quantitative or qualitative measurement of the rates of reactions and provide insight into the dependence of these rates on variables such as concentration temperature pressure the presence of catalysts the physical state of the reactants etcSince chemical reactions are dependent on the concentration of the reactant molecules and the conditions which enable their functional ability understanding the effect of variables on these interactions is critical to controlling the reaction for a successful outcome.

Monowave™ 400200 is a highperformance microwave reactor specially designed for sequential smallscale microwave synthesis applications in research and development laboratoriesInvestigate reaction kinetics and optimize reaction conditions with realtime information about the chemical composition of your reaction.
Reaction kinetics investigate the rate at which reactants disappear or products formThe instantaneous rate is the change in the reactant or product at any given time and is determined by examining the slope of the curve in the plot of concentration vs timeAs an example reactant As instantaneous rate is represented as rate dAdt.
Reaction kinetics provide a measurement of reaction rates factors that affect the speed of a chemical reaction and insight into reaction mechanismsUnderstanding the kinetics of a reaction is critical for being able to control a reaction and direct the desired outcome of the reactionBy testing and identifying how variables affect the rate of a reaction products are optimized and byproducts are reduced.
The course schedule is displayed for planning purposes – courses can be modified changed or cancelledCourse availability will be considered finalized on the first day of open enrollmentFor quarterly enrollment dates please refer to our graduate education section.
The TGA of the undepolymerized PET was performed with TGA equipment SDT Q600 TA Instruments New Castle DE USA at the rate of 10 °C min−1 under a nitrogen environment within the range of 30–700 °CThe SEM JXA840 JEOL Tokyo Japan was used for the morphology analysis of the undepolymerized PET which was put on a specimen stub and deposited by vacuum evaporation with gold.
