Steric factor

  "id": "MLC-T-CHM-011392",
  "term": "Steric factor",
  "field": "Chemistry",
  "definition": "A parameter in collision theory that accounts for the orientation of molecules during a collision, influencing the probability of a reaction occurring. It represents the fraction of collisions that have the correct spatial arrangement for bond breaking and formation. This factor typically ranges from 0 to 1, with values less than 1 indicating that not all collisions lead to a reaction.",
