C6 Reaction Kinetics Flashcards

What is the rate of a reaction?
The rate of a reaction is defined as the change in concentration of a reactant or a product per unit time.
What is the rate equation?
The rate equation is an experimentally determined equation that relates the rate of reaction to the concentrations of the reactants raised to appropriate powers.
What is the order of reaction with respect to a reactant?
The order of reaction with respect to a reactant is the power on its concentration term in the rate equation. The order of reaction must be determined experimentally.
What is the overall order of reaction?
The overall (or total) order of reaction is the sum of the individual orders.
What is the rate constant?
The rate constant, k, is the proportionality constant in the experimentally-determined rate equation. It is a constant at a given temperature.
What is half-life in the context of a reaction?
The half-life, t½, of a reaction is the time taken for the concentration of a reactant to decrease to half its initial value.
