Rate determining step in a reaction consisting of a number of steps in series is the ______________ step?
Correct answer: B. Slowest
- A. Fastest
- B. Slowest
- C. Intermediate
- D. Data insufficient; can't be predicted
Explanation
In the simplified consecutive-step model, the slowest step limits the overall reaction rate and is called the rate-determining step. Faster steps cannot proceed overall faster than this bottleneck.
