This quantity equals molecularity for elementary reactions. For 10 points each:
[10e] Name this quantity, which equals the slope of log-log plots of reaction rate vs. reaction concentration. The half-life of a reaction is constant when this quantity equals 1.
ANSWER: reaction order [or order of reaction]
[10m] This mechanism explains why unimolecular reactions are second-order at sufficiently low pressures using collisions between A, A-star, and M. This mechanism is commonly used to model gas phase decomposition reactions.
ANSWER: Lindemann mechanism [or Lindemann–Christiansen mechanism; or Lindemann–Hinshelwood mechanism]
[10h] Goldfinger, Letort, and Niclause developed a set of rules to calculate reaction order for this process. The Rice-Herzfeld mechanism explains why acetaldehyde undergoing this process has order equal to 3/2.
ANSWER: pyrolysis [prompt on thermal decomposition]
