3.1.9 Rate equations Flashcards
Reaction rate
the change in amount of reactant or product per unit time.
Order of reaction
With respect to a particular reactant, is the power to which the concentration of the reactant is raised in the rate equation.
Rate equation
A + B -> C + D
Rate = k[A]^m[B]^n
Continuous monitoring method
The amount of reactant/product is measured at different time intervals through the course of a single reaction.
Initial rate method
In a series of reactions, initial concentration of one reactant is varied whilst all other concentrations are kept constant.
Reaction mechanism
A series of steps that together make up the overall reaction.
Rate determining step
The slowest step in a reaction mechanism. It determines the reaction rate.
The Arrhenius Equation
k = Ae^(-Ea/RT)
