The main knowledge to know and to understand the applied electrochemistry (primary and Secondary cells, Fuel Cells), kinetics (reactions in solution and in gas phase) and catalysis (homogeneous and eterogeneous catalysis, Langmuir isotherm,enzyme catalysis and the Michaelis Mente mechanism) will be supplied. PREREQUISITES All the skills achieved for the courses of Mathematics Institutions General physics with laboratory General and inorganic chemistry are required. TEACHING METHODS Theory Lessons (40 hours) and some exercises (24 hours). Five experiences in laboratory, both in electrochemistry and in kinetics. SYLLABUS/CONTENT Elettrochemistry electrical condu ctivity in solution. Mobility and transport numbers. Activity and Activity coefficients. electrochemical potential and Nerst equation. Standard electrode potentials. Types of electrodes. Galvanic cells: chemical cells and concentration cells. Applid electrochemistry: primary batteries (Leclanchè, Mallory, Zn-Ag, Zn-aria, litio,), secondary batteries (Pb-acido, Ni-Cd, NiMH, Li ion, Li-S e Na-S). Memort and lazy powder effects. Fuel cells: the fundaments, thermodynamic efficiency; losses. The structure of a fueld cell. General desc ription of the different types of fueld cells. Kinetics Simple order reactions and analysis of the experimental data. The effect of thempersature and the Arrhenius equation. Theories of the chemicsal reaction (Collision Theory and Transition State Theory. Equipotential Energy Surfaces. Some reaction mechanisms in solution and in gas phase (steady state or rate determining step hypoteses ) and some examples (ozone decomposition, HBr synthesis, Hydrogen-oxygen explosive synthesis). Reaction Mechanisms in solution (diffusion, internal pressure, dielectric constant, ionic strengh). Catalysis Homogeneous catalysis (acid-base and proton transfer). Heterogeneous catalysis (physical and chemical adsorption). Langmuir isotherm: simple adsorption, adsorption with dissociation con dissociazione, competitive adsorbption. Enzyme catalysis: Michaelis-Menten mechanism, enzyme inhibition, pH effect. RECOMMENDED READING/BIBLIOGRAPHY P. W. Atkins, J. De Paula, Chimica Fisica, Zanichelli, Bologna, 2004.

ASSESSMENT METHODS It is evaluated the depth and coherence of the acquired knowledge on pure and applied electrochemistry, basic kinetics and catalysis. The oral examination is always conducted by two faculty members and has a duration of at least 30 minutes.
