9. A sample of SO2 is cooled without changing the volume. Which of the following statements concerning the gas after cooling is incorrect? A. The mean free path (distance travelled between collisions) is the same as before. B. The collision frequency (how often molecules collide with each other) is the same as before. C. The SO2 molecules collide with the walls of the container with less force than before. D. The molecules are moving slower than before. 10. H2S is converted into solid sulfur by the Claus process. The reaction equation for the first step of process is: 2 H2S(g) + 3 O2(8) 2 SO2(8) + 2 H2O(g) for which AH° = -1036 kJ. Which one of following statements about this reaction is incorrect? A. The products are lower in energy than the reactants. B. Raising the temperature of the system will increase the value of Kc. C. The products are more stable than the reactants. D. The bonds in the products are stronger than the bonds in the reactants.
