How is the molecularity of a reaction defined?

Options

  1. AThe number of products formed in an elementary reaction.
  2. BThe number of molecules involved in a chemical reaction.
  3. CThe number of reacting species that must collide simultaneously to bring about a chemical reaction.
  4. DThe total number of collisions in a reaction.

Correct answer

C. The number of reacting species that must collide simultaneously to bring about a chemical reaction.

Step-by-step solution

Molecularity of a reaction is defined in the paragraph as the number of reacting species that must collide simultaneously in order to bring about a chemical reaction.
