Single-step reaction

{
  "id": "MLC-T-CHM-010899",
  "term": "Single-step reaction",
  "field": "Chemistry",
  "definition": "A reaction in which the reactants are converted directly into products via one transition state, with no intermediate formed along the way. Its energy profile along the reaction coordinate therefore shows a single maximum, the transition state, whereas a multistep reaction shows one maximum for each step with a valley for every intermediate between them. The reaction is an elementary reaction, and its rate law follows its molecularity.",
