ABSTRACT

C can be broken down into two components: a concentration term relating to the total number, n, of possible sites at which a monomer (atom, molecule) can join the growing cluster, and a frequency factor, f, relating to the probability of a successful incorporation:

C=nf

The number of molecules per unit volume in the liquid state is denoted by n, and the frequency factor, f, can be estimated from the theory of absolute rates.
