For example, thermodynamic data
indicate that diamond shall convert to graphite but
in reality the conversion rate is so slow that the change
is not perceptible at all Therefore, most people think
After studying this Unit, you will be
able to
·
define 
the 
average 
and
instantaneous rate of a reaction;
·
express the rate of a reaction in
terms of change in concentration
of either of the reactants or
products with time;
·
distinguish between elementary
and complex reactions;
·
differentiate 
between 
the
molecularity and order of a
reaction;
·
define rate constant;
·
discuss the dependence of rate of
reactions 
on 
concentration,
temperature and catalyst;
·
derive integrated rate equations
for the zero and first order
reactions;
·
determine the rate constants for
zeroth and first order reactions;
·
describe collision theory Objectives
Chemical Kinetics helps us to understand how chemical reactions
occur 3
