AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the course is to present to the students the fundaments of electrochemistry, kinetics and catalysis. 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). Four 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.

EXAMS

Exam description


Two Written exams during the course: with a mean value for 24/30 or more, it is not necessary the oral exam.

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.
