Abstract
Photochemical reactions do not have a reaction order. If the concentration of the substrate should decrease exponentially with time, that reflects only on the choice of experimental conditions and not on any intrinsic characteristic of the reaction.

Michael HipplerJournal of Chemical Education2003 80 (9), 1074Photochemical Kinetics: Reaction Orders and Analogies with Molecular Beam Scattering and Cavity Ring-Down Experiments
Michael HipplerJournal of Chemical Education2003 80 (9), 1074Despite its fundamental importance, photochemical kinetics is not often treated in much detail in physical chemistry courses and concepts often remain unclear. One topic of recent debate concerns reaction orders of photochemical reactions. In this article,...
