reduction of the photo-active sol is proportional to the intensity of light absorbed by the reaction mixture the quantum efficiency being of the order of o'5 — i'o. [...] Normally it is to be expected that in such simple systems the velocity of reaction should be proportional to the light absorbed by the photo-active sol in the higher state of valency the fraction of the light absorbed by the reduced form of the sol going to waste merely as heat. [...] If the extinction coefficient of the reduced form is of the same order as the original sol the light absorbed by the photo-active sol will continually become less and less during the progress of the reaction. [...] In our studies of the photochemical reduction of these sols which have been described in the previous papers the concentration of the reduced sol at the end of the experiment was often greater than o% of the original sol concentration. [...] The velocity also varies as the square root of light absorbed by the tungstic acid sol and the reciprocal of the velocity plotted against the reciprocal of the concentration of the reductant under otherwise identical conditions gives a straight line.
