A. Fast step
B. Slowest step
C. All steps
D. Molecularity of the reaction
¨ In a reaction that occurs via multiple steps, the overall rate of the reaction is typically determined by the rate of the slowest step, which is also known as the rate-limiting step or the bottleneck step.
¨ The rate of a chemical reaction is determined by the step that has the highest activation energy, as this is the step that will proceed at the slowest rate. The other steps may proceed much faster and may even be in a state of chemical equilibrium, but their rates will not significantly affect the overall rate of the reaction.
¨ Therefore, the overall rate of a reaction that occurs via multiple steps is determined by the rate of the slowest step, which is the step that limits the overall rate of the reaction.
