Molecularity of an elementary reaction, P + Q → R + S is

Answer & Solution
Correct Answer: Option B
The molecularity of an elementary reaction represents the number of molecules or particles that come together to react and form the products. In the given elementary reaction:

P + Q → R + S

There are two reactant molecules (P and Q) that come together to form two product molecules (R and S).

Therefore, the molecularity of this elementary reaction is 2.

So, the correct answer is Option B: 2.

molecularity will be 2, because the probability of 4 molecules colliding at the same time is almost impossible.
