10. INTRODUCTION TO PHYSICAL CHEMISTRY
Physical Chemistry is not a “memory-based”, learn-by-rote discipline, but in centered upon problem-based learning.
Start working on problems with the equation sheet.
View animations and use other web resources.

11. INTRODUCTION TO PHYSICAL CHEMISTRY
Physical chemistry is a study of the physical basis of phenomena related to the chemical composition and structure of substances. Or
Physical chemistry is quantitative and theoretical study of the properties and structure of matter, and their relation to the interaction of matter with energy.

12. INTRODUCTION TO PHYSICAL CHEMISTRY
This course serves as an introduction to chemical thermodynamics, giving u an understanding of basic principles, laws, and theories of physical chemistry that are necessary for chemistry, biochemistry, pre-medical, general science and engineering students.
You will develop the ability to solve quantitative problems and learn to use original thought and logic in the solution of the problems and derivation of equations.
You will learn to apply mathematic in chemistry in such a way that the equations paint a clear picture of the physical phenomena.

13. INTRODUCTION TO PHYSICAL CHEMISTRY
What is Physical Chemistry?
the study of the underlying physical principles that govern the properties & behaviour of chemical systems.
Chemical system
Macroscopic
Large-scale properties of matter
Microscopic
Concepts of molecules

14. AREAS OF PHYSICAL CHEMISTRY
Can be classified into 4 main areas:
Quantum chemistry
(Microscopic)
Statistical mechanics
(Bridge from microscopic to macroscopic)
Thermodynamics
(Macroscopic)
Kinetics
(-rate of process reaction and diffusion
- Highly mathematical)

15. AREAS OF PHYSICAL CHEMISTRY
Quantum chemistry:
application of quantum mechanics to atomic structure, molecular bonding & spectroscopy
Thermodynamics: Macroscopic science that studies:
i. the interrelationships of the various equilibrium properties of a system &
ii. the changes in equilibrium properties in process

16. AREAS OF PHYSICAL CHEMISTRY
Statistical mechanics:
relate quantum chemistry with thermodynamics.
Gives insight into why laws of thermodynamics hold & allows calculation of macroscopic thermodynamic properties from molecular properties.
Kinetics:
study of rate processes.
Examples: chemical reaction, diffusion & flow of charge in an electrochemical cell.

17. THERMO = heat DYNAMICS = power Heat + power + work
Basically concerned with the change of energy
DYNAMICS
= power

18. THERMODYNAMICS Work Energy Heat
Is the study of heat, work, energy and the changes they produce in the state of the systems.
Work is done to achieve motion against an opposing force
Example: process of raising a weight against the pull of gravity
Work
Energy is the capacity to do work
Energy
Heat is the transfer of energy as a results of a temperature difference between the system & it surroundings
Heat

19. Thermodynamic- Basic concepts
Universe
System
Part of the universe under study in thermodynamics
Eg: reaction vessel, engine, biological cell
Surroundings
The region outside the system that can interact with the system

20. Thermodynamic- Basic concepts
Type of system:
Matter
System
System
System
Energy
Energy
Open system
Allow transfer of matter and energy
(can exchange matter & energy)
2. Closed system
Allow transfer of energy
(no transfer of matter
can exchange energy)
3. Isolated system
No transfer of matter and energy
(can exchange neither
energy nor matter)

21. Thermodynamic- Basic concepts
Type of Walls;
Walls: a system may be separated from its surrounding by various kind of walls:
1. a)Rigid – non moveable
b)Nonrigid - movable
2. a)Permeable - matter to pass through
b) Impermeable – matter can’t pass through
3. a) Adiabatic – no transfer or heat
b) Nonadiabatic – energy can pass through

22. Thermodynamic Properties
Composition
Pressure, P is the symbol
Temperature, T is the symbol
Internal energy, U is the symbol
Entropy, S is the symbol
Volume, V is the symbol

23. Thermodynamic Properties
A property can be intensive or extensive
Extensive property : property that depends on size (the amount of substance present in the sample)
Eg: mass, volume, heat
Intensive property: property that is independent of how much (the amount of substance)
E.g., mass density, pressure and temperature)
