  "id": "MLC-T-CHM-004876",
  "term": "Gibbs energy diagram",
  "field": "Chemistry",
  "definition": "A plot of the standard Gibbs energy of a system against a reaction coordinate, illustrating the energy profile of a chemical reaction. The diagram shows the relative Gibbs energy levels of reactants, transition states, reaction intermediates, and products. The highest point on the reaction path between two species corresponds to the transition state, and its energy difference from the reactants defines the Gibbs energy of activation.",
