21. The uncertainty on the rate constants is therefore as important as for that of xenon. 22. Both the high rate constants and the bioorthogonality of SPAAC are amenable to PET chemistry. 23. In this case the rate constant k is equal to the slope with sign reversed. 24. Holding the exchange rate constant is the top priority in a fixed exchange rate regime. 25. SD is the rate constant from the saddle domain. 26. The reaction mechanism includes reactions with the reaction rate constants k _ r > 0. 27. The values of the rate constants through RCl = or are summarized in table 27. 28. Has a rate constant of 2.2?0 " 15. 29. At higher temperatures sulfacetamide solutions degrade to its hydrolysed product, sulphanilamide with a first-order rate constant . 30. The rate constant of the reaction was measured by considering the photon as a third partner.
