  "id": "MLC-T-CHM-007306",
  "term": "Microcanonical rate constant",
  "field": "Chemistry",
  "definition": "A rate constant that is specific to a system with a fixed total energy and number of particles, as described by the microcanonical ensemble in statistical mechanics. It represents the rate of reaction for molecules possessing a precise amount of internal energy. This constant is a fundamental quantity in unimolecular reaction rate theories.",
