Which of the following statements about order of reaction is incorrect?
Correct answer: D. it is always equal to molecularity
- A. It determines mechanism of reaction
- B. It is determined experimentally
- C. It is associated with rate equation
- D. it is always equal to molecularity
Explanation
The order of a reaction can indeed be equal to its molecularity. The order of a reaction refers to the sum of the exponents in the rate equation, which represents how the concentration of reactants affects the rate. Molecularity, on the other hand, refers to the number of reactant particles involved in an elementary step of a 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.
