Case: Read the passage and answer the following questions

A property of a reaction called molecularity helps in understanding its mechanism. The number of reacting species (atoms, ions, or molecules) taking part in an elementary reaction, which must collide simultaneously in order to bring about a chemical reaction is called molecularity of a reaction.

Which of the following is an example of trimolecular reaction?

2NO+O₂ → 2NO₂

Trimolecular or termolecular reactions involve simultaneous collision between three reacting species.
