If the temperature coefficient
of the rate of adsorption
is substantial, an adsorption process is said to be activated (i.e. to have a significant
). In this case, the sticking coefficient
is small. In general, the activation
energy of activated adsorption is a function of coverage and it usually increases
with increasing coverage.
