Abstract: It is shown that thermal dissociation of complex compound ArBs in the
mixture containing components A or В depends on the value of stoichio
metric coefficients r and s. In the systems of the type A— ArBs for s>1 and
В—ArBs for r>1 the degree of thermal dissociation of the complex com
pound at infinite dilution equals one (bx = 1) and the change of mole
fraction of undissociated compound with the change of composition of the
system equals zero. In this case there occurs a minimum on the curve of
dependence of the degree of dissociation on composition of the system.
On the contrary in the system of the type A—ArBs for s=1 and in the
system В— ArBs for r=1 the degree of dissociation of the complex compound monotonously decreases with decreasing content of the compound in
the system and at infinite dilution it approaches to a value which is generally
different from one. The change of mole fraction of undissociated compound
with the change of composition of the system differs from zero in this case.
