Popis:	Equations are derived for obtaining activity coefficients at infinite dilution in binary systems by use of one of the following: (1) an isobaric temperature—liquid composition diagram, (2) an isobaric temperature—vapor composition diagram, (3) an isothermal pressure—liquid composition diagram, or (4) an isothermal pressure—vapor composition diagram. The derived equations are thermodynamically exact, and application involves no doubtful extrapolation of experimental data, as has heretofore been the case. Each equation involves the slope of one of the diagrams at the point corresponding to the pure component. Attention is called to the fact that data on the compositions of both the vapor and liquid phases in equilibrium are not required. Use of the equations is illustrated.
