where k refers to the rate constant for the reaction, t is time, and α and β represent the order of reaction with respect to A and B. Given this representation, the experimental measurement of different species' timescales can be related to the reaction rate. By varying the concentrations of these species we can reveal both the rate constant for this reaction and the order of reaction with respect to each reactant. The rate constant for a reaction is always context-dependent and can depend on factors such as temperature, pH, buffering capacity, and the flux of UV light. For example, Rimmer et al. measured the rate constant for the bimolecular formation of the aminomethanedisulfonate adduct as a function of temperature.
