molecularity

Postby josmit_1D » Mon Mar 09, 2020 2:59 pm

would a termolecular reaction also be considered third order reaction?

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

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 ?

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

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