SCH 303: THERMODYNAMICS II AND PHASE EQUILIBRIA
Course Lecturer: Dr Immaculate Michira
Introduction
Thermodynamics like quantum mechanics is one of the main pillars
of chemistry. It is essentially concerned with the conservation
of energy either in an organized or disorganized form and
possess an immense predictive power. It predicts spontaneous
direction of chemical processes/reactions and the equilibrium
states of chemical systems. It is useful to the chemist, to the
physicists, and to all.
SCH 303 explains and enables the learner to apply the three Laws
of thermodynamics to explain all phenomena in nature.

Course objectives



To emphasize that all physical and chemical processes
involve transfer of energy
To define thermodynamic terms such as system, surroundings,
boundaries, open and closed systems etc.
To evaluate change of internal energy of the system in
terms of the trading currencies i.e heat and work









To establish the advantages of bringing changes to the
system reversibly as opposed to irreversibly
To define systems properties such as U, H, S as path
dependent or exact differentials and the consequences.
To give thermodynamic determinants of spontaneous process
To evaluate the entropy of systems under different
conditions
To define the Gibbs and Helmhotz free energies and
establish their importance
To establish the free energies gives maximum useful work
To explain phase equilibrium in the right of Gibbs free
energy
Derive relevant equations that govern transition of phases
(Clapeyron and the Clausius Clapeyron equation)
To define chemical potential and understand how it can be
extended to understand the thermodynamics of mixtures of
varying compositions (concept of partial molar quantities
and the importance of the Gibbs- Duhem equation).
