Machine-phase chemistry

Guiding reactive moieties along tightly controlled paths …

• can largely suppress unwanted side reactions
• can largely increase rates for the actually desired reaction (higher effective concentration)

Generally this guiding …

• reduces the spacial density (spacial frequency) of active reaction sites
• increases the temporal frequency (temporal density) of reaction events

The latter must and can overcompensate in for the loss in the former.

Actively applying force can accelerate reactions further in some cases.
In some cases applied force can slow down reactions though. See: Inter system crossing.
Higly exoergic >>kT reactions with no energy recuperation will typically happen fast.
Energy recuperation (and maybe even dissipation sharing to squeez out as much efficiency as possible)
will change reaction range rates in nontrivial ways.
