Reaction barrier

{
  "id": "MLC-T-CHM-009963",
  "term": "Reaction barrier",
  "field": "Chemistry",
  "definition": "The energy maximum along the minimum energy pathway connecting reactants to products in a chemical reaction. This energy difference, often referred to as the activation energy, must be overcome for the reaction to proceed. The height of the reaction barrier determines the rate of a chemical reaction.",
