Question:
Which of the following statements is NOT correct regarding order of reaction?
Which of the following statements is NOT correct regarding order of reaction?
Show Hint
Order of reaction is experimental and can be fractional; Molecularity is theoretical and always a whole number.

- It is determined experimentally.
- It is not influenced by stoichiometric coefficient of reactants.
- It is sum of power to the concentration terms of reactants in rate law equation.
- It is always whole number.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
The order of a reaction is an experimental quantity that defines the dependence of the reaction rate on the concentration of reactants.
Step 2: Analysis
- Statement (A), (B), and (C) are fundamental properties of the order of reaction. - Order of reaction can be zero, a whole number, or even a fraction.
Step 3: Conclusion
Therefore, the statement that it is "always a whole number" is incorrect.
Final Answer: (D)
