  "id": "MLC-T-CHM-011646",
  "term": "Surface excess Gibbs energy",
  "field": "Chemistry",
  "definition": "The excess Gibbs energy associated with the formation of an interface between two phases, relative to the Gibbs energy of the bulk phases. It represents the work required to create a unit area of new surface at constant temperature and pressure. This thermodynamic quantity is directly related to surface tension in liquid-vapor interfaces.",
