Rate determining step is also called?
Correct answer: B. Rate Limiting step
- A. Critical step
- B. Rate Limiting step
- C. Final Step
- D. None of these
Explanation
The rate-determining step is also called the slowest step because it is the step with the highest activation energy and the slowest rate. This step limits the overall rate of the reaction and determines the rate law of the reaction. The rate law is an expression that relates the rate of the reaction to the concentration of reactants and catalysts, and the temperature of the reaction.

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.
