  • Gibbs Free Energy
    A thermodynamic quantity used to predict if a reaction can occur without external input, reflecting both enthalpy and entropy changes.
  • Spontaneous Reaction
    A process that proceeds on its own, increasing disorder and requiring no outside energy to occur.
  • Entropy
    A measure of disorder or randomness, with higher values indicating more disordered systems.
  • Delta G
    A value representing the change in free energy during a reaction, indicating favorability and direction.
  • Standard Free Energy Change
    A reference value for spontaneity, calculated under set temperature and pressure, allowing comparison between reactions.
  • Exergonic Reaction
    A process that releases energy, resulting in products with lower free energy than reactants and a negative free energy change.
  • Endergonic Reaction
    A process that absorbs energy, producing products with higher free energy than reactants and a positive free energy change.
  • Equilibrium
    A state where forward and reverse reactions occur at equal rates, causing no net change in reactant or product concentrations.
  • Equilibrium Constant
    A ratio reflecting the relative amounts of products and reactants at equilibrium, used to predict reaction direction.
  • Directionality
    The tendency of a reaction to proceed toward either products or reactants, influenced by the equilibrium constant.
  • Steady State
    A condition where concentrations of reactants and products remain stable over time, despite ongoing input or output.
  • Thermodynamic Favorability
    A characteristic of processes that can occur without external energy, often associated with increased disorder and energy release.
  • Reactant
    A starting substance in a chemical process, whose transformation leads to product formation.
  • Product
    A substance formed as a result of a chemical process, present after the transformation of reactants.
