Introduction
 Processing of materials (pure and mixtures) is
key affair in chemical processes
 Estimation of many properties (and change)
other than volumetric properties (H,U,s,G etc.)
are required.
 How to know complete property set when
volumetric properties are not available
 What tools can one use to handle such issues?

Property Relations for Homogeneous Phases
Fundamental Properties
ü Although equation (6.1) is derived from the special case of
a reversible process, it not restricted in application to
reversible process.
ü It applies to any process in a system of constant mass that
results in a differential change from one equilibrium state to
another.
ü The system may consist of a single phase or several
phases; may be chemically inert or may undergo chemical
reaction.
