Collisions in Unimolecular Reactions

Postby Jessica Li 4F » Mon Mar 09, 2020 5:14 pm

In class today, Lavelle brought up how in reactions, the reactants need to collide with enough energy (activation energy) for the reaction to proceed. How does this apply to unimolecular reactions, where there is only one reactant and it doesn't need to collide?

The reactant would still collide with solvent molecules, but that is not shown in the rate law.

Dr. Lavelle said that in unimolecular reactions the molecule does not have to collide with other molecule. The molecule can collide with the side of the beaker or with solvent that is not a part of the chemical reaction. These collision can cause bond breaking in that one molecule resulting in unimolecular reaction
