Calculations succeed in reproducing experimentally reported reaction times. The procedures are mostly standard, coupled with some sensitive choices in terms of starting concentrations and dielectric constant. This means that these particular reactions accelerated by ball milling follow the same mechanism as the equivalent reactions in solution
