  "id": "MLC-T-CHM-009965",
  "term": "Reaction cross-section",
  "field": "Chemistry",
  "definition": "A measure of the probability that a specific chemical reaction will occur when two particles collide. It represents an effective area that the target particle presents to the incident particle for a reaction to take place. The reaction cross-section is typically expressed in units of area, such as square meters or barns.",
