Description
This is the first of a two-part survey of physical chemistry. Topics are selected from the broad themes of
the discipline: thermodynamics, chemical kinetics and their applications to chemistry. Physical chemistry
uses differential and integral calculus extensively. Calculus 2101 was therefore required as a prerequisite.
The co-requisite laboratory component (CHEM3335) is aimed to reinforce the subject matter learnt in
lectures.
Objectives
This course seeks to:
● Apply thermodynamic and kinetic principals to chemical reactions
● Grasp the fundamental difference between thermodynamic and kinetic approaches in chemistry
● Apply the concepts and principles to solve practical problems.
Learning Outcomes
Knowledge
On successful completion of this course, students will be able to:
● calculate P (or V or T) of an ideal gas or ideal gas mixture, perform calculations involving
differentiation (ordinary and partial derivations), use of and 
to find volume changes produced by
changes in T or P.
● use the first law of thermodynamics to calculate heat (q), work (w), change of the internal energy
(∆U) and enthalpy (∆H) for different thermodynamic processes (isobaric, isothermal, adiabatic,..).
● use the second law of thermodynamics to calculate entropy change (∆S) for different reversible
processes (phase change, constant-pressure heating, change of state of a perfect gas, mixing perfect
gases at constant T and P)

Lecture Quizzes
There will be a number of random quizzes directly after completion of each chapter for a short time which
counts 10% toward the final course mark.
Tests
There will be at least two mid-term tests, each of 75 minutes duration. These tests will count 40% toward
