Question

Which of the following values of the molecularity are not possible?

• A. $0$
• B. $2$
• C. $3$
• D. $4$

Answer 1

Answer: (A), (D)

$0$
$4$

Molecularity is the no. of molecules of reactants colliding simultaneously to form product. So, it cannot be zero. Also, there is very less probability that 4 molecules will collide simultaneously. Hence, molecularity can also not be 4.
