The order of a chemical reaction is__________________?
Correct answer: B. An experimentally determined quantity
- A. Always equal to the total stoichiometric number of reactants
- B. An experimentally determined quantity
- C. Never fractional
- D. None of these
Explanation
Reaction order comes from the experimentally determined rate law, not directly from the stoichiometric equation. It may also be zero, fractional, or even negative in some systems.
