  • Patent number: 9632095
    Abstract: A method of determining the activation energy Ea for degradation of a chemical species includes in sequence the steps of a) simultaneously incubating a plurality of samples of the chemical species in a single unitary device at a plurality of constant temperatures T, in each case for an incubation time t selected to result in loss of at most 20 mol % of the amount originally present; b) quenching each of the samples 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; d) determining for each sample a reaction rate coefficient kobs according to the equation k obs ? ( T ) = 1 - m ? ( T ) t ; and e) performing numerical regression of the kobs values obtained in step d) and the corresponding temperatures T in ° K to derive the activation energy Ea according to the following equation k obs = k 0 ? exp ? ( E a R ? ( 1 T - 1 T 0 ) ) , or t
