Terms in this set (15)

  • Equilibrium
    A state in a chemical reaction where the rates of the forward and reverse reactions are equal.
  • Equilibrium Constant
    A value that expresses the ratio of product concentrations to reactant concentrations at equilibrium.
  • Thermodynamics
    The study of energy changes, particularly the direction of a chemical reaction at equilibrium.
  • Kinetics
    The study of the rate or speed at which reactants are converted into products.
  • Reactants
    Substances initially present in a chemical reaction that are consumed during the reaction.
  • Products
    Substances formed as a result of a chemical reaction.
  • Pressure
    The force exerted by gas particles per unit area, affecting equilibrium in gaseous reactions.
  • Volume
    The space occupied by a gas, influencing equilibrium when changed in a reaction.
  • Inert Gas
    A gas that does not react with other substances and can affect equilibrium under certain conditions.
  • Catalyst
    A substance that increases the rate of a reaction without being consumed, not affecting equilibrium.
  • Activation Energy
    The minimum energy required for a chemical reaction to occur, lowered by catalysts.
  • Temperature
    A measure of thermal energy that affects the direction of equilibrium shifts in reactions.
  • Exothermic Reaction
    A reaction that releases heat, causing equilibrium to shift away from heat when temperature increases.
  • Endothermic Reaction
    A reaction that absorbs heat, causing equilibrium to shift toward heat when temperature decreases.
  • Le Chatelier's Principle
    A principle stating that a system at equilibrium will adjust to counteract any imposed change.
