Why does reducing solute particle size increase the speed at which the solute dissolves in water? A. It exposes more of the solute to the water molecules. B. It makes the temperature of the water significantly higher. C. It raises the pressure of the water molecules on the solute. D. It makes the water molecules move around faster.

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
