Question
Colligative properties depend on A. the chemical properties of the solute. B. the chemical properties of the solvent. C. the masses of the individual ions. D. the molar mass of the solute. E. the number of particles dissolved. Two aqueous solutions are prepared: 1.00 m Na_2CO_3 and 1.00 m LiCl. Which of the following statements is true? A. The Na_2CO_3 solution has a higher osmotic pressure and higher vapor pressure than the LiCl solution. B. The Na_2CO_3 solution has a higher osmotic pressure and lower freezing point than the LiCl solution. C. The Na_2CO_3 solution has a lower osmotic pressure and lower vapor pressure than the LiCl solution. D. The Na_2CO_3 solution has a lower osmotic pressure and lower freezing point than the LiCl solution. E. None of these statements is true. Which of the following statements is TRUE? A) The rate constant does not depend on the activation energy B) A catalyst increases the activation energy of a reaction. C) Rate are temperature dependent. D) The addition of a homogeneous catalyst does not change the activation energy of a given reaction. E) None of the above are true. The decomposition of hydrogen peroxide is a fine-order process with a rate constant of 1.06 times 10^-1 min^-1. How long will it take for the concentration of H_2O_2 to drop form 0.0200 M to 0.0120 M? A.Explanation / Answer
Q16.
colligative properties depend mainly in the SOLVENT
therefore the chemical properties of the solvent are the important ones to study
Of course the amount of solute matters, but note that the solutes are interchangeable
