Effect of a Catalyst on Equilibrium Chemical Equilibrium Dimensionless A catalyst changes how quickly equilibrium is reached but never where that equilibrium lies. K unchanged

Enzyme Biochemistry & Polymer Chemistry Dimensionless A biological catalyst, almost always a protein, that accelerates a specific biochemical reaction.

Effective Collision Chemical Kinetics & Catalysis Dimensionless A collision that actually leads to reaction because it has both sufficient energy and correct orientation.

Enzyme Specificity Biochemistry & Polymer Chemistry Dimensionless The ability of an enzyme to select one substrate, or one class of substrate, and catalyse one particular reaction.

Equilibrium Constant Chemical Equilibrium Various The fixed ratio of product to reactant terms, each raised to its stoichiometric power, that characterises a reaction at a given temperature. K = Π[products]^ν / Π[reactants]^ν

Equilibrium Yield Chemical Equilibrium Dimensionless The proportion of reactant converted to product once equilibrium has been reached. yield = n_product / n_theoretical

Esterification Stoichiometry & Chemical Reactions Dimensionless The acid-catalysed condensation of a carboxylic acid with an alcohol to form an ester and water. RCOOH + R′OH ⇌ RCOOR′ + H₂O
