Unformatted text preview: Which of these aqueous solutions has the highest boiling point? 0.100m CaCl 2 Which of the following 0.1M aqueous solutions would have the lowest freezing point? Al(NO 3 ) 3 Which of the following statements concerning graphical methods for determining reaction order is false? For a second-oder reaction the plot of [A] 2 vs. time gives a straight line Consider the exothermic combustion of coal. Which of the following could increase the rate of reacton. Raising the temperature Which produces the greatest van't Hoff factor when one mole dissolves in water. Na 2 SO 4 produces 3 As the temperature of a reaction increases, the rate of the reaction increases because THE reactant molecules collide with greater energy per collison Based on our knowledge of colligative properties, which of the following is TRUE – The vapor pressure above a solution is less than the vapor pressure of the pure solvent at the same conditions. The new movement of solvent molecules through a semipermeable membrane can be stopped by – Applying Pressure After four half life periods for a first order reaction. What fraction remains – 6.25% The solubility of gases in aqueous solutions decreases with increasing temperature Molality is the concentration expressed as number of moles per kg of solvent.Molality is the concentration expressed as number of moles per kg of solvent....
