Problem
When an elementary step in a reaction mechanism is identified as the rate-limiting step, which statement best describes how the rate law for the overall reaction is obtained?
(a) It is the sum of the individual rate laws for every elementary step in the mechanism.
(b) It is determined by the fastest elementary step because that step forms products first.
(c) It is determined solely by the molecularity of the rate-limiting elementary step.
(d) It is determined by the stoichiometric coefficients in the balanced overall equation.
