E1 Reaction
A two-step elimination proceeding through a carbocation, which then loses a proton to form an alkene.
Organic ChemistryE2 Reaction
A single-step elimination in which a base removes a proton as the leaving group departs, forming a double bond.
Solutions & Colligative PropertiesEbullioscopic Constant
The boiling point elevation produced by a one-molal solution of a non-electrolyte in a given solvent.
Chemical EquilibriumEffect 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.
Inorganic & Coordination ChemistryEffective Atomic Number Rule
The observation that stable metal carbonyls tend to have a total electron count equal to that of the next noble gas.
Chemical Kinetics & CatalysisEffective Collision
A collision that actually leads to reaction because it has both sufficient energy and correct orientation.
Atomic Structure & PeriodicityEffective Nuclear Charge
The net positive charge actually experienced by a particular electron after allowing for shielding by other electrons.
Stoichiometry & Chemical ReactionsEffervescence
The rapid escape of gas bubbles from a liquid during a chemical reaction.
States of Matter & Gas LawsEffusion
The escape of gas molecules one at a time through a hole much smaller than the mean free path.
Electrochemistry & RedoxElectrochemical Cell
A device in which a redox reaction and an electric current are interconverted through two separated electrodes.
Electrochemistry & RedoxElectrochemical Equivalent

Electrochemistry & RedoxElectrode
A conductor through which electric current enters or leaves an electrolyte.
Electrochemistry & RedoxElectrolysis
The decomposition of an electrolyte by passing an electric current through it.
Electrochemistry & RedoxElectrolyte
A substance that produces mobile ions when dissolved or molten and therefore conducts electricity.
Electrochemistry & RedoxElectrolytic Cell
An electrochemical cell in which an external electrical supply drives a non-spontaneous redox reaction.
Electrochemistry & RedoxElectrolytic Conductivity
The ability of an electrolyte solution to conduct electric current, equal to the reciprocal of its resistivity.
Electrochemistry & RedoxElectromotive Force
The maximum potential difference a cell can produce, measured when no current is being drawn.
Atomic Structure & PeriodicityElectron
A negatively charged fundamental particle that occupies orbitals around the nucleus and governs chemical bonding.
