Rate Constant Chemical Kinetics & Catalysis Various The proportionality constant in a rate law, characteristic of a given reaction at a given temperature. k = A e^(−Ea/RT)

Reagent Foundations of Chemistry Dimensionless A substance added to a system to bring about a chemical reaction or to test for the presence of another substance.

Relationship between K and Rate Constants Chemical Equilibrium Various The equilibrium constant of an elementary reaction equals the ratio of its forward and reverse rate constants. K = k_forward / k_reverse

RNA Biochemistry & Polymer Chemistry Dimensionless A generally single-stranded nucleic acid that carries out the expression of genetic information.

Transition State Chemical Kinetics & Catalysis kJ/mol The highest-energy configuration along the reaction coordinate, at which bonds are partly broken and partly formed. denoted ‡

Turnover Number Chemical Kinetics & Catalysis s⁻¹ The number of substrate molecules converted per catalytic site per unit time. TON = molecules converted / active sites

Zero-Order Reaction Chemical Kinetics & Catalysis mol/(L·s) A reaction whose rate is independent of the concentration of the reactant. [A] = [A]₀ − kt
