Stoichiometry 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 Solute concentration Both A & B Neither A nor B Temperature Solute concentration Both A & B Neither A nor B Temperature ANSWER DOWNLOAD EXAMIANS APP
