Thermodynamics and kinetics

Use of the basic principles of equilibrium thermodynamics to be able to predict whether a reaction is possible, in which direction it is spontaneous and determine from the equilibrium constant the proportions of reactants at equilibrium. Application to homogeneous and heterogeneous equilibria and to the particular cases of precipitation reactions.(acid-base and redox reactions if time permits). Hourly volume: 19,5 h.

In a second part, the kinetic aspects and therefore the speed of reaction will be discussed. Only simple reaction orders will be studied during this year. Hourly volume: 7,5 h .

Use thermodynamic data (enthalpy, entropy, heat capacity, etc.) to determine, in the case of homogeneous and heterogeneous equilibria, the direction of spontaneous evolution of a chemical reaction, to calculate the equilibrium constant of this chemical reaction and to predict the quantities or proportions of the different reactants. To know the influence of the parameters temperature, pressure and composition on a chemical equilibrium and to be able to use them to move this equilibrium in a given direction. Calculate the pH of acidic or basic solutions and mixtures. Interpret and/or calculate the evolution of the pH of a solution during a titration.

Be able to calculate a simple chemical reaction rate and identify the factors that influence it.

Determine the direction of spontaneous evolution of a chemical reaction, calculate the equilibrium constant, determine the quantities of reactants at equilibrium and the speed at which they will appear in the medium.

It is necessary to have previously followed a thermodynamics module. It is imperative to know the vocabulary and to know how to use the first two principles of thermodynamics.

Mathematics at the final year level and more particularly knowing how to use derivatives and usual integrals.
