Reaction Rate
The change in concentration of reactants or products per unit time.
Rate Law
A mathematical expression that relates reaction rates to reactant concentrations.
Differential Rate Law
Rate depends on concentration.
Integral Rate Law
Obtained by integrating the differential rate law; concentration depends on time.
Reaction Order
The exponent to which a reactant's concentration is raised in the rate law; indicates how the rate is affected by the concentration of that reactant.
Rate Constant (k)
The proportionality constant in the rate law that relates the rate of reaction to the concentrations of reactants.
Method of Initial Rates
A method used to determine the rate law by comparing the initial rates of a reaction at different initial concentrations of reactants.
