Created by StemPy LabTwo liquids give out heat when mixed, and the volume of the mixture is less than the sum of the two volumes. Which statement about the solution is correct?
← All Quizzes
← 308 g of carbon tetrachloride, molar mass 154 g/mol, holds 16.0 g of a non-volatile solute of molar mass 64 g/mol. Pure carbon tetrachloride has a vapour pressure of 15.3 kPa at 298 K. What is the vapour pressure of the solution?Statement I: A pair of liquids with a large positive deviation from Raoult's law can form a minimum-boiling azeotrope. Statement II: A positive deviation means a higher vapour pressure than Raoult's law, so the mixture boils at a lower temperature. Which choice is correct? →
