Learning objectives
The course provides the theoretical and practical aspects of chemical kinetics and for this includes both classroom lessons and laboratory exercises. The topics covered provide the bases of chemical kinetics for a correct understanding of the course of reactions according to the parameters that govern their velocity, in particular concentration of the reagents, temperature, and presence of catalytic species.
Expected learning outcomes
Student will be able to:
- set the kinetic study of a chemical and/or catalytic reaction with obtaining the significant parameters related to the reaction rate and to its dependence on temperature
- organize the experimentation for the kinetic study of chemical reactions
- draw up a technical-scientific report on experiences carried out in a chemical laboratory
- collaborate with colleagues in a group work.
Course syllabus and organization

Single session

Responsible
Lesson period
Second semester
Course syllabus
Reaction rate. Rate equation and rate constant. Order reaction and molecularity. Integrated kinetic equations for the principal order reactions (zero order-, first order-, second order-, and nth order- reactions). Half-period of reaction. Determination of the reaction order: integral method, differential method, half-period method, and isolation method. Consecutive reactions and the steady-state approximation. Parallel reactions. Opposing and equilibrium reactions.
Dependence of the rate constant on temperature. Arrhenius equation. Eyring equation and transition state theory. Catalysed reactions. Homogeneous catalysis.
Practical experiments: isothermal reactions in batch reactors with homogeneous catalysts in aqueous liquid phase and in organic solvent; reaction taking place with linearly increasing temperature.
Prerequisites for admission
Knowledge of the main concepts of differential and integral calculus. Computer knowledge for the use of spreadsheet.
Teaching methods
Teaching will take place through lectures and practical laboratory exercises aimed at providing knowledge and operational tools, if possible.
The didactic material and the proposed operational tools will be made available in digital format so that students can rework them according to their teaching needs.
Teaching Resources
- P. Atkins, J. De Paula, Elements of Physical Chemistry, Zanichelli, 2007, Chapters 10 and 11; or other editions for the relevant chapters of the course topics.
- Course notes on the ARIEL_UNIMI platform to all UNIMI students.
Assessment methods and Criteria
Written report on the work done in the laboratory; group work for the part of the experimentss carried out in presence and single work for the part of the mathematical-kinetic elaborations. Oral exam on all aspects of the course, chemical and applied kinetics. Students will have to demonstrate that they understand the fundamentals of chemical kinetics and that they are able to develop the main kinetic equations, to know how to apply them logically. Students will have access to the oral exam only if the report on the work done in the laboratory and/or the mathematical-kinetic elaborations have been judged positively.
