The effect of a changing composition of e.g. the liquid phase is related to the scaling factors for viscosity, temperature and pressure, and that is the corresponding state principle. The reference viscosity correlation of Pedersen et al. (1987) [ 18 ] is
The distribution constant (or partition ratio) (K D) is the equilibrium constant for the distribution of an analyte in two immiscible solvents. [1] [2] [3]In chromatography, for a particular solvent, it is equal to the ratio of its molar concentration in the stationary phase to its molar concentration in the mobile phase, also approximating the ratio of the solubility of the solvent in each phase.
The RD-100 performed admirably, and low-pressure LOX/Ethanol engine development continued, in the form of the RD-102 and RD-103. However, the development of high-pressure engine technology allowed propellants with a higher energy density to be used, and so LOX/Kerosene quickly replaced LOX/Ethanol as the propellant of choice.

For elements that have multiple allotropes, the reference state usually is chosen to be the form in which the element is most stable under 1 bar of pressure. One exception is phosphorus, for which the most stable form at 1 bar is black phosphorus, but white phosphorus is chosen as the standard reference state for zero enthalpy of formation. [2]
