Question:
Which among the following is a false statement?
Which among the following is a false statement?
Show Hint
Molecularity is always a positive integer, indicating the number of molecules involved in an elementary reaction step.
Updated On: Feb 28, 2025
- Rate of zero order reaction is independent of initial concentration of reactant.
- Half-life of a zero order reaction is inversely proportional to the rate constant.
- Molecularity of a reaction may be zero.
- For a first order reaction, \( t_{1/2} = 0.693/k \).
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Molecularity refers to the number of reacting species in an elementary reaction, and it cannot be zero. A reaction cannot take place without any reacting molecules.

- Correct statements regarding Arrhenius equation among the following are:
Factor \(e^{-E_a/RT}\) corresponds to fraction of molecules having kinetic energy less than \(E_a\).
At a given temperature, lower the \(E_a\), faster is the reaction.
Increase in temperature by about \(10^\circ\text{C}\) doubles the rate of reaction.
Plot of \(\log k\) vs \(\dfrac{1}{T}\) gives a straight line with slope \(= -\dfrac{E_a}{R}\).
