rate law (empirical differential rate equation)
An expression for the
rate of reaction
of a particular reaction in terms of concentrations of
chemical species
and constant parameters (normally
rate coefficients
and partial
orders of reaction
) only. For examples of rate laws see equations (1)-(3) under
kinetic equivalence
, and (1) under
steady state
.
