Consider a solution made from a nonvolatile solute and a volatile solvent. Which statement is true? A) The vapor pressure of the solution is always greater than the vapor pressure of the pure solvent. B) The boiling point of the solution is always greater than the boiling point of the pure solvent. C) The freezing point of the solution is always greater than the freezing point of the pure solvent. The following data were obtained for the reaction of NO with O2. Concentrations are in molecules /cm3 and rates are in molecules /cm3s. 9. What is the order of the reaction with respect to NO? 10. What is the order of the reaction with respect to O2 ? 11. What is the rate law? 12. A chemical reaction that is first order in X is observed to have a rate constant of 1.710251. If the initial concentration of X is 1.0M, what is the concentration of X after 190s
