Chemical Equilibrium
12 terms
Effect of a Catalyst on Equilibrium
A catalyst changes how quickly equilibrium is reached but never where that equilibrium lies.
Chemical EquilibriumEffect of an Inert Gas
The influence of adding a non-reacting gas on the position of a gaseous equilibrium.
Chemical EquilibriumEffect of Concentration Change
The shift in equilibrium position caused by adding or removing a reactant or product.
Chemical EquilibriumEffect of Pressure Change
The shift in a gaseous equilibrium caused by changing the total pressure through a volume change.
Chemical EquilibriumEffect of Temperature Change
The shift in equilibrium caused by heating or cooling, which uniquely also changes the equilibrium constant.
Chemical EquilibriumEquilibrium Constant
The fixed ratio of product to reactant terms, each raised to its stoichiometric power, that characterises a reaction at a given temperature.
Chemical EquilibriumEquilibrium Constant of a Reversed Reaction
The constant obtained when a reaction is written in the opposite direction, equal to the reciprocal of the original.
Chemical EquilibriumEquilibrium Constant of a Scaled Reaction
The constant obtained when every coefficient in an equation is multiplied by the same factor.
Chemical EquilibriumEquilibrium in Closed Systems
The requirement that no matter enters or leaves for a true chemical equilibrium to be established.
Chemical EquilibriumEquilibrium Position
The particular set of concentrations at which a system settles, describing how far the reaction has proceeded.
Chemical EquilibriumEquilibrium Yield
The proportion of reactant converted to product once equilibrium has been reached.
Chemical EquilibriumExtent of Reaction
A single variable measuring how far a reaction has progressed from pure reactants towards products.
