Critical Temperature States of Matter & Gas Laws K The temperature above which a gas cannot be liquefied by pressure alone, however great. T_c = 8a / 27Rb Dalton's Law of Partial Pressures States of Matter & Gas Laws Pa The total pressure of a gas mixture equals the sum of the pressures each component would exert alone in the same volume. p_total = p₁ + p₂ + p₃ … Diastereomer Organic Chemistry Dimensionless A stereoisomer that is not a mirror image of the compound with which it is compared. Dilution Solutions & Colligative Properties mol/L The process of reducing a solution's concentration by adding more solvent, leaving the amount of solute unchanged. M₁V₁ = M₂V₂ Disaccharide Biochemistry & Polymer Chemistry Dimensionless A carbohydrate formed when two monosaccharide units join through a glycosidic bond. C₁₂H₂₂O₁₁ Distribution Law Chemical Equilibrium Dimensionless The principle that a solute distributes itself between two immiscible solvents in a constant ratio at fixed temperature. K_D = C_organic / C_aqueous Effect of an Inert Gas Chemical Equilibrium Pa The influence of adding a non-reacting gas on the position of a gaseous equilibrium. Effect of Pressure Change Chemical Equilibrium Pa The shift in a gaseous equilibrium caused by changing the total pressure through a volume change. shift towards fewer gas moles when p rises Electron Domain Geometry Chemical Bonding & Molecular Structure degrees The spatial arrangement of all electron domains — bonding and lone pairs alike — around a central atom. Electrophile Organic Chemistry Dimensionless An electron-deficient species that seeks and accepts a pair of electrons from an electron-rich centre. E⁺ Electrophoresis Analytical Chemistry & Spectroscopy cm/s A separation technique in which charged species migrate through a medium under an applied electric field. v = μE Elementary Reaction Chemical Kinetics & Catalysis Dimensionless A reaction that occurs in a single step exactly as written, with no detectable intermediate. order = molecularity Empirical Formula Foundations of Chemistry Dimensionless The chemical formula giving the simplest whole-number ratio of atoms of each element in a compound. ratio = (mass % ÷ A_r), normalised Entropy Thermochemistry & Thermodynamics J/(mol·K) A measure of the dispersal of energy and the number of microscopic arrangements available to a system. S = k ln W Formula Unit Foundations of Chemistry Dimensionless The simplest whole-number ratio of ions represented in the empirical formula of an ionic or network compound. Functional Group Isomerism Organic Chemistry Dimensionless Structural isomerism in which compounds of the same formula contain entirely different functional groups. Gaseous State States of Matter & Gas Laws Dimensionless The state of matter in which particles are widely separated and move randomly at high speed, filling any container completely. pV = nRT Gay-Lussac's Law of Combining Volumes Stoichiometry & Chemical Reactions L The principle that gases react in volume ratios that are simple whole numbers, when measured at the same temperature and pressure. V_A : V_B = a : b Gay-Lussac's Pressure Law States of Matter & Gas Laws Pa/K At constant volume, the pressure of a fixed mass of gas is directly proportional to its absolute temperature. p₁ / T₁ = p₂ / T₂ Glucose Biochemistry & Polymer Chemistry g/mol The most abundant monosaccharide and the primary energy source for most living cells. C₆H₁₂O₆ Graham's Law of Diffusion States of Matter & Gas Laws Dimensionless The rate at which a gas diffuses or effuses is inversely proportional to the square root of its molar mass. r₁ / r₂ = √(M₂ / M₁) Halogens Atomic Structure & Periodicity Dimensionless The group 17 elements — fluorine through astatine — which are one electron short of a full outer shell. ns² np⁵ Heat Capacity at Constant Volume Thermochemistry & Thermodynamics J/(mol·K) The heat needed to raise a system's temperature by one kelvin while its volume is held fixed. C_V = (∂U/∂T)_V Homogeneous Catalysis Chemical Kinetics & Catalysis Dimensionless Catalysis in which the catalyst is in the same phase as the reactants.
