The order of a reaction:
AIs always equal to 1 for gaseous reactions
BEquals the molecularity of the rate-determining step always
CMust always be a positive integer
DCan be zero, fractional or negative — it is experimentally determined
Answer & 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.
