insignicant or can be shown to be either quasi-steady
or partial equilibrium (PE). On the other hand, the sys-
tem parameters can show high sensitivity to certain
reactions that can be identied as rate-limiting reac-
tions. The sensitivity of a system response parameter
y with respect to the perturbation of the reaction rate
constant k of a reaction is dened as ∂y/∂k. Its lognormal
form, ∂ ln y/∂ ln k, measures the relative error induced
by the removal of this reaction. Reactions with sensitiv-
ity smaller than certain specied values can be consid-
ered to be unimportant and hence neglected.
The reaction ow analysis determines the character-
istic reaction pathways and helps identify the dominant
reaction path ...
