← ScienceWhich consequence results when excessive vibrational energy affects unimolecular decomposition?
A)Increased rate constant beyond limits✓
B)Catalyst poisoning becomes accelerated significantly
C)Equilibrium shifts favoring reactants more
D)Activation energy barrier reduction increases mildly
💡 Explanation
The Lindemann mechanism governs unimolecular reactions; because excessive vibration concentrates energy, it raises reaction probability far above predictions, therefore unexpectedly spiking the observed rate constant, rather than merely shifting equilibrium or slightly influencing the activation energy.
