Aims

The main aim of this module is to equip students with an understanding of basic kinetics and thermodynamics as they relate to chemical reactions.


Learning Outcomes

(LO1) By the end of the module students should be familiar with, and be able to make appropriate use of the basic ideas of chemical thermodynamics

(LO2) By the end of the module students should be familiar with, and be able to make appropriate use of ideas relating to the rates of chemical reactions

(LO3) By the end of the module students should have developed basic laboratory skills and be able to write simple experimental reports which include data and error analysis.

(S1) By the end of the module students will have developed their problem-solving skills

(S2) By the end of the module students will have developed their organisational skills


Teaching and Learning Strategies

Overview. The module will consist of 24 in-person lectures (12 on thermodynamics and 12 on kinetics), 5 problem-solving workshops, and the laboratory work and supporting workshops.
There will be a 1 hr class test part way through the course.

Lectures. All material is covered in Elements of Physical Chemistry (P.W. Atkins and J. de Paula).
Students will be expected to be able to use various equations from a formula sheet [integrated rate laws, temperature dependence of rate constants and equilibrium constants, and so on] without having been exposed to full derivations.

Practical. A number of the thermodynamics and kinetics concepts will be illustrated by experiments carried out under close demonstrator supervision.
PC sessions will be used to provide support with the analysis of the experimental results.
Some experiments will be conducted in pairs, to further interaction skills.
The students will write (individually) a report on their experimental work , which will be assessed.

Workshops. Students will have the opportunity in the workshops to work through problems that relate to the principles covered in the lectures with the support of tutors. Learning is supported in Canvas by on-line quizzes to be taken following completion of the workshops.

*Lectures: 24 hr
*Practical: 21 hr
*Coursework: 10 hr


Syllabus

 

Lecture Material

Thermodynamics [mostly energy changes in chemical reactions] (Dr Johnson)
•Ideal gas equation, including definitions/units of pressure, temperature, mole and standard conditions and use of pV=nRT and deviations from the ideal gas equation.
•The First Law of Thermodynamics: Types of thermodynamics functions. Internal energy and enthalpy; heat & work; Measurement of energy and enthalpy using calorimeters.
•Enthalpies of reaction.
•The Second Law of Thermodynamics. Equilibrium as a minimum in Gibbs Free Energy.
•The relationship between entropy and order
•Entropies and Gibbs Free Energies of Reaction
•Concept of equilibrium being minimum in the Gibbs free energy. Idea of extent of reaction. Reaction Quotient and Equilibrium constant.
•Relationship between Equilibrium Constant and Gibbs free energy.
•Equilibria in Solutions: solubility products, acid-base rea ctions, buffer solutions, electrochemical reactions (including Nernst Equation).
•Variation of equilibrium constant with temperature.

Kinetics (Dr Volk)
•concept of chemical reaction rates;
•reaction orders and rate laws; rate constant; pseudo-order reactions;
•initial rates method;
•integrated rate equations for 0th order, 1st order and (simple) 2nd order reactions and their application;
•half-life;
•kinetic measurements;
•temperature dependence of chemical reaction rates; Arrhenius equation, activation energy and their determination from experimental data;
•elementary step; collision geometry and energy barrier; solvent cage;
•reaction mechanism of more complex reactions, rate-determining step; equilibrium;•catalysis, including examples for heterogeneous catalysis (Haber process, catalytic converter) and homogeneous catalysis (enzymes - Michaelis-Menten mechani sm).

Workshop Material
•The lecture course will be supported by workshop sessions designed to give students an opportunity to practise solving kinetics and thermodynamics problems

Laboratory Material
•In the laboratory sessions, students will carry out a mixture of kinetics and thermodynamics experiments. These experiments have been designed to allow students to finish the experimental work in one three-hour session. Supporting workshops introduce students to the necessary data analysis and report writing skills. There are compulsory pre-lab activities associated with each practical session.
