TRUE OR FALSE 1. The bacterial reactions that lead to the spoiling of milk proceed much slower at room temperature than they do at a lower temperatures of refrigerators. 2. A medicine in the form of a tablet will dissolve in the stomach and enter the bloodstream more slowly than the same medicine in the form of a fine powder. 3. The rates of many reactions can be increased by adding a catalyst. 4. The rates of chemical reactions increase as temperature is increased. 5. Most of the chemical reactions proceed faster if the concentrationnof one or more of the reactants is decreased. 6. Change in Freezing point is equal to the sum of the freezing point of the solution and the pure solvent. 7. Kb is the ratio of the boiling point elevation to the molal concentration an extremely dilute solution. 8. The boiling point of a solution of a non-volatile solute is higher than that of a pure solvent. 9. Relative lowering in the vapor pressure of dilute solution is equal to the mole fraction of the solute present in the solution. 10. Mole fraction is the ratio of moles of the solute to the moles of the solvent.
