  Recently, we have shown that thermal effects play a crucial role in speeding
up the rate of bond-dissociation reactions. This was done by applying a simple
temperature-shifted Arrhenius Law to the experimental data, corroborated with
detailed account of the heat diffusion occurring within the relevant samples
and identification of errors in the temperature measurements. Here, we provide
three important extensions of our previous studies. First, we analyze thermal
effects in reduction-oxidation (redox) reactions, where charge transfer is an
integral part of the reaction. Second, we analyze not only the spatial
distribution of the temperature, but also its temporal dynamics. Third, we also
model the fluid convection and stirring. An analysis of two exemplary
experimental studies allows us to show that thermal effects can explain the
experimental data in one of experiments (Baumberg and coworkers), but not in
the other (Jain and coworkers), showing that redox reactions are not
necessarily driven by non-thermal charge carriers.
