1. Explain what changes in the state of a gas brings about each of the following effects?
a. The number of impacts per unit time on a given container wall increases.
b. The average speed of molecules in the gas mixture is increased.
c. The average energy of impact of molecules with the wall of the container decrease.
2. The molecules of the vapor phase are found to effuse through a tiny hole at the 0.28 times the rate of effusion of Ar atoms under the same conditions of temperature and pressure. Arsenic (III) sulfide sublimes readily, even below its melting point of 320oC. Determine the molecule formula or Arsenic (III) sulfide in the gas phase?
