Abstract: The generalized form of the LeChatelier--Shreder equation and relation for the limiting value (for x_eq approaching to 1) of temperature variation of the degree of dissociation of A_qB_r in an A-A_qB_r system at the dystectic melting point were used to calculate the limit of temperature variation of ''weighted-in'' mole fraction of A_qB_r at the dystectic melting point during permanent phase equilibrium. it was proved that this limit is infinite and thus the tangent line to the liquidus curve at the dystectic melting point is parallel to the composition axis.
