Fundamental relations *The thermodynamic functions: the Helmholtz energy, the pressure, the enthalpy, the Gibbs energy The molecular partition function: the translational contribution the rotational contribution, the vibrational contribution, the electronic contribution, the overall partition function 2. Using statistical thermodynamics Mean energies: the mean translational energy, the mean rotational energy, the mean vobrational energy Heat capacities: the individual contributions, the overall heat capacity Equations of state Residual entropies Equilibrium constants: the relation between K and the partition function, a dissociatio equilibrium, contributions to the equilibrium constant Part 3 Change Part 3 considers the processes by which change occurs. We prepare the ground for a discussion of the rates of reactions by considering the motion of molecules in gases and in liquids. Then we establish the precise meaning of reaction rate, and see how the overall rate, and the complex behaviour of some reactions, may be expressed in terms of elementary steps and the atomic events that take place when molecules meet. Characteristic physical and chemical events that take place at surfaces, including catalysis, and we see how to describe them. 11 The rates of chemical reactions（6 hours） I.
