Worked practice questions

The order of a reaction:

  1. Is always equal to 1 for gaseous reactions
  2. Equals the molecularity of the rate-determining step always
  3. Must always be a positive integer
  4. Can be zero, fractional or negative — it is experimentally determined
Show answer and solution

Correct answer: D. Can be zero, fractional or negative — it is experimentally determined

Order is experimentally determined and can be zero (e.g. NO₂ + CO → ... in CO), fractional (e.g. 3/2 for CH₃CHO decomposition) or even negative.
