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.
