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.”
