Laboratory of Physical Chemistry
A.Y. 2022/2023
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
Reaction rate. Equation of velocity and constant of velocity. Order of reaction and molecularity. Integrated kinetic equations for the main reaction orders (zero order, first order, second order, and nth order of reaction). Semi-transformation time. Determination of the order of reaction: integral method, differential method, half-life method, and isolation method. Consecutive reactions and steady-state approximation. Parallel reactions. Opposite and equilibrium reactions.
Dependence of the speed constant on the temperature. Arrhenius equation. Eyring equation and transition state theory. Catalyzed reactions. Homogeneous catalysis. Acid-base catalysis.
Practical experiments in the laboratory: isothermal reactions carried out in batch reactors with homogeneous catalysts in an aqueous liquid phase and in organic solvent and reaction carried out with a linear increase in temperature.

Prerequisites for admission
Knowledge of the main notions of differential and integral calculus. Computer knowledge for the use of programs with spreadsheets (e.g., Excel, Origin)
Teaching methods
Teaching will take place both through lectures and through 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.

Assessment methods and Criteria
Written group report on the work carried out in the laboratory exercises and oral examination on all aspects carried out in the classroom and in the laboratory. Students will have to demonstrate that they have understood the fundamentals of chemical kinetics and that they are able to develop the main kinetic equations, to be able to apply them logically.
