Molecularity

[ian_haliburton_1f]

Does anyone know the term for when 4 molecules are required to collide? In other words, what comes after termolecular?

[Kate Chow 4H]

A guess, but I would assume tetramolecular.

[Joon Chang 2F]

Yes I think a reaction that involves four molecules colliding simultaneously would be called a tetramolecular reaction. Given that termolecular reactions are uncommon due to three molecules having to collide simultaneously, tetramolecular reactions would be very rare.
