Termolecular Molecularity

Postby Drew Myers 4G » Sun Mar 08, 2020 9:56 pm

Can someone give an example of an elementary step that has termolecular molecularity and give its rate law?

A termolecular elementary step is any combination of three molecules colliding. This is very unlikely, and termolecular reactions are rare.

The reason termolecular reactions are so rare is that three molecules must collide simultaneously for it to occur. The more molecules needed, the lower the probability of the reaction occurring, which is why termolecular reactions are very uncommon.

Since gas molecules move randomly, the chances of 3 colliding simultaneously is very very low.

Termolecular molarity is very rare.

Do y'all think this will be on the final?
