molecularity

[josmit_1D]

would a termolecular reaction also be considered third order reaction?

[Naneeta Desar 1K]

Yes termolecular would be considered a 3rd order reaction I believe. However these are very uncommon.

[Brian J Cheng 1I]

As Naneeta says, they're uncommon. Dr. Lavelle specifically told us to focus on 0, 1, and 2 order reactions (zero order, unimolecular, and bimolecular). Zero order == nonmolecular?

I think a zero order reaction would just have no molecularity at all.

Is molecularity then just the amount of reactants that interact?

Yep! Unimolecular = 1 molecule
Bimolecular = 2 molecules need to collide to react
etc etc etc.

For molecularity, is there such thing beyond termolecular ?

[Amanda Lin 2I]

If there is, it would be rare because the molecules would need to collide simultaneously.

[ShravanPatel2B]

Yes it would be a third order. But we should be focusing on 0,1,2 orders so until bimolecular.
