Main themes
Three general topics are presented:
  •  An introduction to the understanding of matter structure and properties which leads to study the structure of atoms, the periodicity of atomic properties, intra- and inter-molecular bonds and how they control the structure of materials.
  • An introduction to thermodynamics within the frame of physical and chemical equilibrium, in a rigorous way but without necessarily using the complete formalism of thermodynamics; the approach is based on the atomic structure of matter and ideas derived from statistical physics. This includes state variables, the first principle of thermodynamics (energy conservation, internal energy, enthalpy, heat and enthalpy of reaction), the second principle of thermodynamics (spontaneous and non-spontaneous processes, entropy), free energy (including its interest to describe equilibrated reactions and its link to equilibrium constants). The notion of ideal gas will also be briefly introduced.
  • How these notions are of interest to understand one-component phase transformations and chemical equilibria in aqueous solutions, such as acid/base reactions and solubility equilibria.

Content
The course LEPL1301 Chemistry and Physical Chemistry 1 is the first course of chemistry and physical chemistry in the civil engineering curriculum.
The first part of the course focuses on the introduction to chemistry and the basic concepts that allow the solution of "chemical problems" (notions of atom, molecule, chemical notation, mole, concentration, reaction energy, reaction yield, limiting reactant, etc.). It continues with an understanding of matter from the microscopic to the macroscopic. This first leads to the study of the structure and properties of atoms and ions. The chemical bounds between atoms to form molecules and the associated energies are then presented.
On this basis, the second part of the course focuses on the thermodynamic description of phase and chemical equilibria. To do this, after a description of the properties of perfect gases, it develops the concepts of work, heat, enthalpy, statistical entropy, thermodynamic entropy and free enthalpy. From the criteria of spontaneous evolution based on these notions, it establishes the formalism describing equilibria (equilibrium constants, free enthalpies of reaction) and applies it to the study of equilibria involving pure solids, pure liquids and gases.
Based on the notions of chemical equilibrium and equilibrium constant, the third part of the course deals with the concepts of acids and bases. Thermodynamics, in particular equilibrium constants, is used to study quantitatively the strength of acids and bases. Chemical equilibria in the aqueous phase are then discussed and illustrated through the study of acid-base titrations and solubility equilibria.
Teaching methods
The teaching consists of lectures and group-based learning through exercises (APE) and problems (APP). The PBL sessions are conducted in the presence of tutors who ensure that the students are encouraged to think through and solve the problem or exercise and through this work learn the concepts involved. Some parts of the course are given in a flipped classroom format.
Evaluation methods
At the end of each part, depending on the possibilities left by the timetable, a possible short online test is organised (each teacher will confirm whether and how these tests will be held). If they are organised, the online tests will cover the learning, lectures, PBLs of each part. If the student is successful, these tests will give a maximum bonus of 2 points for the part concerned.
The in-session written examination covers the entire semester material. For the examination, students receive, together with the questionnaire, a copy of the periodic table of elements and a copy of the forms established by the teachers, previously available on the Moodle site of the course. All the data needed to solve the problems numerically are provided with the questionnaire. The examination is organised in the form of an multiple choice questionnaire.
In order to ensure that the final grade for the course reflects a minimum level of competence acquired in each of the three parts of the course, the overall examination grade will be calculated on the basis of the geometric mean of the grades obtained for the three parts (a possible zero in one part is converted into a non-zero grade in order to calculate this mean). It will be established as follows
  • the mark for each part will be the examination mark plus the possible "bonus" of the online test (max 2 points), limited to 20/20 ;
  • the overall examination mark will be calculated on the basis of the geometric average of the marks obtained for the three parts and will be rounded to the nearest whole number.
