Document Summary

Department name & course number: chem 1001 a and t. Students must count the number of pages in this examination question paper before beginning to write, and report any discrepancy immediately to a proctor. This examination paper may not be taken from this examination room. A periodic table and list of constants appears on page 11. You may tear off page 11 if you wish. Answer all twelve questions with a few sentences or equations (5 marks each). This is because the rate of diffusion is related to the average speed of the molecules, which is related to the square root of the inverse of the molecular weight. Because the temperature is the same, the kinetic energy is the same (3. 74 kj mol-1). Average kinetic energy is not related to the molecular weight. This is due to increasing nuclear charge going left to right. Both of these molecules are trigonal pyramidal, and so are polar.
