What is the speed of rate determining step?
Correct answer: B. Slow and decreasing
- A. Very fast and increasing
- B. Slow and decreasing
- C. Moderate and decreasing
- D. Continuously increasing
Explanation
The speed of the rate-determining step is slow. The rate-determining step is the slowest step in a reaction mechanism. This means that it is the step that limits the overall rate of the reaction. The rate of the rate-determining step is determined by the activation energy of the step.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
