Meaning of deactivation energy | Babel Free

Definitions

The amount of energy needed to slow down or stop a reaction.

physical

Examples

“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.”

“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).”

“However, in the first case (deactivation energy << main reaction energy) there appears to be a uniform variation of activity throughout the bed.”

“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.”
