- 1992, International journal of chemical kinetics, page 1110:
- The decomposition of peroxydisulfate to sulfate radical ions was taken to be a rapid preequilibrium, and was postulated to be followed by the rate-determining reaction of a sulfate radical ion with MG to produce a radical intermediate, I.
- 2009, Stephen J. Lippard, Current Research Topics in Bioinorganic Chemistry, Volume 18:
- In cases involving multiple preequilibria (e.g., multiple substrates, induced conformational change), K.,, reveals little about each of these steps individually. In the case of allosteric interaction, characteristic kinetic behavior is...
