    Energy associated with a chemical reaction that can be used to do work.
  • Redox Reaction
    A chemical reaction involving the transfer of electrons between two species.
  • Electrochemical Cell
    A device that generates electrical energy from chemical reactions.
  • Anode
    The electrode where oxidation occurs in an electrochemical cell.
  • Cathode
    The electrode where reduction occurs in an electrochemical cell.
  • Activity Coefficient
    A factor used to account for deviations from ideal behavior in solutions.
