The rate of conversion for a reaction occurring in a closed system is defined as the
time derivative of the
extent of reaction:
In view of the definition of
extent of reaction it follows that with reference to any species in a reaction showing time-independent
stoichiometry
where
is the amount of the species at any time
and
is its
stoichiometriccoefficient.
