Or in other words: the bulk of the work is already automated! The conditions have been set up and the reactants are doing the work of reacting. There’s nothing for the experimenter to do but wait.

The reaction can’t be sped up, its rate is wholly constrained by the nature of the compounds involved and the physical parameters of the experiment, which may be very narrow to avoid unwanted products or even thermal runaway which could cause a total failure of the experiment or even a dangerous release of poisonous or explosive materials.
