CHIMICA ORGANICA - ELEMENTI DI CHIMICA FISICA

Module ELEMENTI DI CHIMICA FISICA

Knowledge and understanding: the student acquires the knowledge of the basic laws of chemistry and physics necessary to understand the origin and evolution of chemical, biochemical and biological phenomena and their applications in the pharmaceutical field.

Ability to apply knowledge and understanding: the student acquires the principles of thermodynamics and how these allow or set limits in the various energy transformations.

Learning skills: the student becomes able to apply chemical-physical models for the rationalization of experiments.

Making judgments: after consolidating the basic concepts, the student develops his critical ability in evaluating and interpreting the data that allow him to independently undertake subsequent research in the chemical-pharmaceutical sector.

Lectures and numerical exercises on the basic concepts and on the many and applications in the chemical-pharmaceutical field.

If lectures are given in a mixed or remote way, some changes may be introduced from what has been stated above, in order to comply with the program and visaged and reported in the syllabus.

Attendance of lessons is required in accordance with the regulation of the CdS as reported in the link: http://www.dsf.unict.it/corsi/l-12_sfa/piani-di-studio.

THERMODYNAMICS

The first law of thermodynamics. Work and Heat. State functions: internal energy, enthalpy, heat capacity at constant pressure and volume. Thermochemistry. Standard enthalpy, enthalpy of reaction, enthalpies of formation, bond energy endothermic and exothermic processes The Hess's law.

The second principle of thermodynamics. Entropy and spontaneous processes. Absolute entropy. Gibbs free energy. Gibbs energy dependence on pressure. Chemical equilibrium. Thermodynamic equilibrium constants. Homogeneous and heterogeneous equilibria. Effect of temperature on equilibrium. 

ELECTROCHEMISTRY

Conductivity of electrolyte solutions, conductometry and conductometric titrations. Electrodic potentials, half-cells, batteries, Nernst equation. Standard reduction potentials and its applications in chemistry and biochemistry. Potentiometry.

CHEMICAL KINETICS

Rates of chemical reactions, reaction order. Integrated form of the kinetic equations of zero, first and second order. Parallel-competitive reactions, consecutive reactions and reactions at the equilibrium. Reaction mechanisms and reaction order. Catalysis.

The written test requires the resolution of three numerical exercises on the following topics:

chemical kinetics;

first law of thermodynamics;

second law of thermodynamics;

electrochemistry. 

Verification of learning can also be carried out electronically, if the conditions require it.
