Q1: In case of a ternery system involving two liquid components and a solute, the ratio of the concentration of the solute in the two phases at equilibrium is called the distribution co-efficient. The distribution co-efficient depends upon the

ANS:C - both(a) & (b)

The distribution coefficient, also known as the partition coefficient, is indeed the ratio of the concentration of a solute in two immiscible phases (typically a solid phase and a liquid phase, or two different liquid phases) at equilibrium. This coefficient is influenced by several factors, but primarily it depends on the solute concentration and temperature.

• Solute Concentration: The distribution coefficient is influenced by the initial concentration of the solute in the system. Higher initial concentrations may lead to higher partition coefficients.
• Temperature: Temperature affects the solubility of the solute in the phases, thus influencing the distribution coefficient. In general, as temperature increases, the solubility of many solutes increases, leading to changes in the distribution coefficient.
