deactivation energy

English

Noun

deactivation energy (plural deactivation energies)

The amount of energy needed to stop an atomic system.
- 1971, Geomagnetism and Aeronomy - Volume 11, page 427:
  If we disregard the deactivation energy, which can be done, except, perhaps, for the lowest vibrational levels, then, according to Bates' theoretical computations, the atom-exchange rate constant must be large, ~10^-10 cm³sec^-1.
- 2004, Icelandic Agricultural Sciences - Volumes 16-20, page 46:
  Activation energy is a measure of the minimum energy needed by the photosynthesis system to react and deactivation energy is the maximum energy the system can cope with before the reaction decreases (Brady 1990).
- 2012, John Butt, Activation, Deactivation, and Poisoning of Catalysts, page 372:
  However, in the first case (deactivation energy << main reaction energy) there appears to be a uniform variation of activity throughout the bed.
- 2016, Jorge Ancheyta, Deactivation of Heavy Oil Hydroprocessing Catalysts, page 267:
  The highest deactivation energy was obtained for hydrodenitrogenation of the nonbasic nitrogen (33.8 kcal/mol), while the deactivation energies for the other reactions were in the range of 20–27 kcal/mol.
