In this paper we consider the dynamics of colloid particle interaction, meaning that we take transient disequilibration of double layers into account. The adsorption-desorption process for charge-determining ions is investigated as rate-determining. The rate constant k(des) for desorption is the most critical characteristic. Depending on its value relative to the interaction time, a range of interaction types can be found between the limits "at constant chemical potential" with Deborah’s number De --> 0 (k(des) --> infinity) and "at the constant charge" with De --> infinity (k(des) --> 0). A dynamic discrimination can also be made between long-distance and short-distance interaction, Elaborations on the influence of the rate of disequilibration on the interaction Gibbs energy between spherical particles are given for the cases of low and high surface potential and further consequences for the dynamics of interaction are discussed, There are indications that the experimentally observed insensitivity of the stability ratio W to the particle radius may also have a dynamic origin.
