Physical Chemistry
Introduction
INTRODUCTION
Scientific Law a summary of experience
hypothesis a guess at an explanation in terms of
more fundamental concepts
theory when the hypothesis has become
established it is promoted to a theory
Physical Chemistry establishes and develops the
principles that are used to explain and interpret
the observations made in the other branches of
chemistry.
The study of the underlying physical principles
that govern the properties and behavior of
chemical systems.

Physical Chemistry
Introduction
Physical Chemistry

• the discussion of bulk properties in terms of
  thermodynamics
• the use of spectroscopy to explore the behavior
  of individual atoms and molecules
• the analysis of the rates and mechanism of
  chemical change

Physical Chemistry provide a framework for all
branches of chemistry

Physical Chemistry
Introduction
Thermodynamics
The principal application of the first law in
chemistry
First Law expresses the conservation of energy
Thermochemistry
Gibbs Energy
Second Law expresses the observation about the
direction of natural change
Entropy

Physical Chemistry
Introduction
Physical Chemistry
Thermodynamics?Studies the interrelationships of
the various equilibrium properties of a system
and the changes in equilibrium properties in
processes (1-14)
Quantum Mechanics?The motions of molecules and
the electrons and nuclei that compose them are
governed by the laws of quantum mechanics (18).
Quantum Chemistry?Application of quantum
mechanics to atomic structure, molecular bonding,
and spectroscopy (19-21)
Statistical Mechanics?Gives insight into why the
laws of thermodynamics hold and allows
calculation of macroscopic thermodynamic
properties from molecular properties (15-16,
22-24)
Kinetics?Study of rate processes such as chemical
reactions, diffusion, and the flow of charge in
an electrochemical cell, uses relevant portions
of thermodynamics, quantum chemistry, and
statistical mechanics (16-17, 23)
