  "id": "MLC-T-CHM-006642",
  "term": "Line-of-centres model",
  "field": "Chemistry",
  "definition": "A simplified model in chemical kinetics that describes the collision between two reacting molecules, assuming that reaction only occurs if the collision energy along the line connecting their centers exceeds a certain threshold. This model provides a basic framework for understanding activation energy. It is a variant of collision theory.",
