P&I 3 - Kinetics

Sampling and quenching

is a method used in reaction kinetics to obtain a snapshot of the concentration of reactants and products at a specific time during a reaction. This technique involves rapidly stopping the reaction, typically by cooling or adding a chemical that halts the reaction process.

Order of reaction

refers to the power to which the concentration of a reactant is raised in the rate law. It indicates how the reaction rate depends on the concentration of that reactant.

General rate equation =

k[A]^{^m}[B]^{^n}

True or false you can work out orders of reactions from stoichiometry

False; reaction orders may not directly correlate with stoichiometric coefficients.

Rate of reaction

is the change in concentration of a reactant or product per unit time.

rate determining step

is the slowest step in a reaction mechanism that determines the overall rate of the reaction.

Arrhenius equation

k = Ae^{^(-Ea/RT)}
