Rate law: r = k [A]ᵐ [B]ⁿ. Sum m + n is called:
AOrder of reaction
BMolecularity
CStoichiometry
DHalf-life
Answer & Solution
Correct answer: A. Order of reaction
Order of reaction = sum of exponents of concentrations in the rate law. Determined experimentally, NOT from stoichiometry. Can be integer, fractional, or zero.
