Critical energy

{
  "id": "MLC-T-CHM-002685",
  "term": "Critical energy",
  "field": "Chemistry",
  "definition": "The minimum internal energy that a molecule must possess to undergo a specific unimolecular reaction, such as dissociation or isomerization. This energy corresponds to the energy of the transition state for the reaction pathway. It is a fundamental parameter in chemical kinetics, influencing reaction rates and product distributions.",
