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)
Rate Law
Chemical Kinetics & Catalysis
mol/(L·s)
An experimentally determined equation expressing reaction rate as a function of reactant concentrations.
rate = k[A]^m[B]^n
Rate-Determining Step
Chemical Kinetics & Catalysis
Dimensionless
The slowest step in a reaction mechanism, which limits the overall rate.
Reaction Intermediate
Chemical Kinetics & Catalysis
mol/L
A species produced in one step of a mechanism and consumed in a later one, so it does not appear in the overall equation.
Reaction Mechanism
Chemical Kinetics & Catalysis
Dimensionless
The detailed sequence of elementary steps by which reactants are converted into products.
Reaction Rate
Chemical Kinetics & Catalysis
mol/(L·s)
The change in concentration of a reactant or product per unit time.
rate = −Δ[A]/(aΔt) = Δ[P]/(pΔt)
