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 Both A & B Temperature Solute concentration Neither A nor B Both A & B Temperature Solute concentration Neither A nor B ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry At a constant volume, for a fixed number of moles of a gas, the pressure of the gas increases with rise of temperature due to Decrease in mean free path Increased collision rate among molecules Increase in molecular attraction Increase in average molecular speed Decrease in mean free path Increased collision rate among molecules Increase in molecular attraction Increase in average molecular speed ANSWER DOWNLOAD EXAMIANS APP
