The element oxygen has 2 stable molecular forms (called allotropes)—O2 and O3. However, nitrogen does not have a stable N3 form. Draw the Lewis structure of N3, and use the structure to briefly explain why it is unstable. Question to consider: What feature of a molecule’s Lewis structure corresponds to its instability (or higher reactivity) ?

Sulfur is allotropic -- two crystalline forms of the element are stable under conditions not far from standard. The transition temperature from rhombic to monoclinic sulfur is 95.4 ˚C; the enthalpy of transition is 0.38 kJ per mol of sulfur atoms. Monoclinic sulfur melts at 119 ˚C; the enthalpy of fusion is 1.23 kJ per mol of sulfur atoms. (a) Calculate the entropy change accompanying each of these phase transitions per mole of S atoms. (b) Consider then that these...

For the reaction NO + O3 → NO2 + O2 the second order rate constant has a value of 1.8x10^-14 molecule-1 cm3 s-1 at 25°C. The concentration of NO in a relatively clean atmosphere is 0.10 ppbv (parts per billion by volume) and that of O3 is 15 ppbv. Calculate these two concentrations in units of molecule cm-3. Calculate the rate of the NO oxidation using concentration units of molecule cm-3. Show how the rate law may be expressed in...
