Which 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.
