Academic Year 2010/2011

  • Docente: Claudio Degli Esposti
  • Credits: 5
  • SSD: CHIM/02
  • Language: Italian
  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: First cycle degree programme (L) in Chemistry and Materials Chemistry (cod. 8006)

Learning outcomes

The course provides the basic physicochemical concepts for the study of reaction rates and electrochemical processes, and an overwiev of the main experimental techniques employed. The students will learn how a reaction kinetics can be experimentally studied, and in which way the corresponding measurements must be analysed.

Course contents

Empirical chemical kinetics. Dependence of the reaction rates on reactant concentrations. The main experimental methods used to determine the order of reactions and rate constants. Dependence of the rate constants on the temperature. Transition-state theory. Elementary and composite reactions. Mechanisms of consecutive, simultaneous, and chain reactions. Homogeneous and heterogeneous catalysis. Adsorption. Reactions on solid surfaces. Applications of  heterogeneous catalysis. Electric conductivity of ionic solutions. Thermodynamical basis of electrochemistry. Reversible and irreversible electrochemical cells. Cell reaction. EMF of a cell and thermodynamical parameters. EMF and standard electrode potentials. Concentration cells. Polarization and overvoltage. Electrolysis. Combustion cells. Rechargeable batteries.
