Terms in this set (14)

  • Thermodynamics
    Branch of physical science focused on energy transformations and the movement toward equilibrium in reactions.
  • Spontaneous Reaction
    Process that occurs naturally without the need for continuous external energy input, moving toward equilibrium.
  • Non-Spontaneous Reaction
    Process requiring ongoing external energy to proceed; ceases immediately when energy input stops.
  • Equilibrium
    State in which a reaction's forward and reverse processes occur at equal rates, resulting in balance.
  • Kinetics
    Study of reaction rates, independent of whether a process occurs naturally or requires energy input.
  • Delta G
    Thermodynamic variable indicating the free energy change, used to predict if a reaction is spontaneous.
  • Delta S
    Thermodynamic variable representing entropy change, contributing to the prediction of reaction spontaneity.
  • K
    Equilibrium constant reflecting the ratio of product to reactant concentrations at equilibrium.
  • Natural Process
    Event or reaction that occurs on its own under given conditions, without external energy supply.
  • Unnatural Process
    Event or reaction that does not occur on its own and requires continuous energy to proceed.
  • Energy Transformation
    Conversion of one form of energy into another during physical or chemical changes.
  • Momentum
    Property allowing objects, like a boulder, to continue moving without additional energy input.
  • Physical Science
    Field encompassing the study of non-living systems, including energy changes in chemical reactions.
  • Balanced Equation
    Representation of a chemical reaction showing equal numbers of each atom on both sides, reflecting conservation.
