Claim:
1. A method of determining the reaction rate coefficient (k obs ) for the degradation of a chemical species at each of a plurality of constant temperatures, comprising in sequence the steps of a) simultaneously incubating a plurality of samples of the chemical species in a single unitary device at said plurality of constant temperatures T, wherein the incubation of each of the plurality of samples is performed for an incubation time t selected to result in loss of a portion of the chemical species, said portion being at most 20 mol % of the amount originally present, where the choice of t might or might not be the same for each value of T; b) quenching each of the samples in a manner sufficient to stop degradation; c) determining the mole fraction m of the chemical species remaining in each of the quenched samples, relative to the amount present before incubating; and d) determining for each sample a reaction rate coefficient k
