  • Energy Diagram
    A curved plot showing energy changes of reactants, products, and the highest energy point during a chemical reaction.
  • Reactant
    A starting substance in a chemical reaction, represented at the enough-left side of an energy diagram.
  • Product
    A substance formed at the end of a chemical reaction, shown at the far-right side of an energy diagram.
  • Transition State
    The maximum energy structure between reactants and products, located at the characteristic peak of an energy diagram.
  • Activated Complex
    A fleeting, high-energy arrangement of atoms at the top of the energy curve, identical to the transition state.
  • Reaction Coordinate
    The x-axis of an energy diagram, representing the progress or lifetime of a chemical reaction.
  • Activation Energy
    The minimum energy difference between reactants and the transition state, determining how fast a reaction proceeds.
  • Energy Barrier
    Another term for the minimum energy required to convert reactants into products, equal to activation energy.
  • Overall Energy Change
    The difference in energy between products and reactants, indicating reaction favorability and stability.
  • Enthalpy
    A measure of thermal energy change during a reaction, with negative values indicating heat release.
  • Gibbs Free Energy
    A value indicating the favorability of product formation; negative values mean a reaction is spontaneous.
  • Exothermic Reaction
    A process where thermal energy is released, resulting in products with lower energy than reactants.
  • Endothermic Reaction
    A process where thermal energy is absorbed, resulting in products with higher energy than reactants.
  • Exergonic Reaction
    A reaction with a negative Gibbs free energy, favoring product formation and greater stability.
  • Endergonic Reaction
    A reaction with a positive Gibbs free energy, not favoring product formation and resulting in less stability.
