Basic Concepts in Chemical Kinetics—Determination of the Reaction Rate Expression

This chapter defines a number of terms that are used by the chemical kineticist and treats some of the methods employed in the analysis of laboratory data to determine empirical rate expressions for the systems under investigation. [Pg.24]

It is convenient to approach the concept of reaction rate by considering a closed, isothermal, constant pressure homogeneous system of uniform composition in which a single chemical reaction is taking place. In such a system the rate of the chemical reaction (r) is defined as [Pg.24]

Several facts about this definition should be noted. [Pg.24]

The rate is defined as an intensive variable. Note that the reciprocal of system volume is outside the derivative term. This consideration is important in treating variable volume systems. [Pg.24]

The definition is independent of any particular reactant or product species. [Pg.24]
