title: Graphical analysis of the formation function-I The real cross-over point.
abstract: From a mathematical treatment, it has been proved that a family of formation curves shows a real cross-over point in the following cases: (a) a mixture of mononuclear complexes BA, BA(2) ... BA(N) and polynuclear complexes of general formula (B(q)A(p))(n), provided that p/q < N; (b) a mixture of homonuclear complexes B(Q)A(p), where Q is constant, and mononuclear complexes shows at least one cross-over point if the maximum value for p is smaller than NQ and at least two cross-over points if NQ lies between the minimum value and the maximum value for p. Curves calculated for three different examples are in perfect agreement with the theory.
