Chemical Equilibrium
60 terms · page 2 of 3
Equilibrium 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.
Chemical EquilibriumHeterogeneous Equilibrium
An equilibrium involving species present in more than one phase.
Chemical EquilibriumHomogeneous Equilibrium
An equilibrium in which all the reacting species are present in the same phase.
Chemical EquilibriumICE Table
A systematic tabulation of Initial, Change and Equilibrium amounts used to solve equilibrium problems.
Chemical EquilibriumIonic Equilibrium
An equilibrium involving ions in solution, such as the dissociation of weak electrolytes or the dissolution of sparingly soluble salts.
Chemical EquilibriumIonic Product
The product of the ion concentrations actually present in a solution, each raised to its stoichiometric power.
Chemical EquilibriumIonic Strength
A measure of the total concentration of ionic charge in a solution.
Chemical EquilibriumLaw of Mass Action
The principle that the rate of a reaction is proportional to the product of the active masses of the reactants.
Chemical EquilibriumLe Chatelier's Principle
When a system at equilibrium is disturbed, it responds in the direction that partially opposes the disturbance.
Chemical EquilibriumMagnitude of K and Extent of Reaction
The use of the size of the equilibrium constant to judge how far a reaction proceeds before equilibrium is reached.
Chemical EquilibriumMole Fraction Equilibrium Constant
The equilibrium constant written in terms of the mole fractions of the reacting gases.
Chemical EquilibriumOptimum Conditions for Industrial Yield
The compromise set of temperature, pressure and catalyst chosen to balance equilibrium yield against reaction rate and cost.
Chemical EquilibriumOverall Formation Constant
The equilibrium constant for the formation of a complex directly from the free metal ion and all its ligands.
Chemical EquilibriumPartition Coefficient
The equilibrium ratio of a solute's concentrations in two immiscible phases.
Chemical EquilibriumPerturbation and Re-equilibration
The disturbance of an equilibrium followed by its relaxation to a new equilibrium state.
Chemical EquilibriumPhase Equilibrium
The condition in which two or more phases of a substance coexist with no net transfer between them.
Chemical EquilibriumPhysical Equilibrium
An equilibrium between two physical states or phases of the same substance.
Chemical EquilibriumPredicting Precipitation
The use of the ionic product and solubility product to decide whether a solid will form on mixing two solutions.
Chemical EquilibriumPressure Equilibrium Constant
The equilibrium constant for a gaseous reaction expressed in terms of partial pressures.
Chemical EquilibriumReaction Quotient
The same ratio as the equilibrium constant but evaluated with the concentrations actually present at any moment.
Chemical EquilibriumRelationship between K and Rate Constants
The equilibrium constant of an elementary reaction equals the ratio of its forward and reverse rate constants.
Chemical EquilibriumRelationship between Kp and Kc
The conversion linking the pressure and concentration forms of the equilibrium constant for a gaseous reaction.
