Kinetics Flashcards
what are orders of a reaction used for
Orders of reaction are used to relate the rate of a reaction to the reacting species.
how can the order of a reaction be determined
The order of a reaction can only be determined from experimental data.
what step of the reaction determines the rate equation
The rate of reaction is dependent on the slowest step, which is called
the ‘rate determining step’.
what is it called when reactions have multiple steps
Reactions usually occur by a series of steps called a reaction
mechanism.
how can the rate equation and the rate constants be determined
The rate equation and the rate constant, including units, can be determined from initial rate data for a series of reactions in which the initial concentrations of reactants are varied.
what does the rate of a chemical reaction normally depends
The rate of a chemical reaction normally depends on the concentrations of the reactants.
how do reactions usually occur
Reactions usually occur by a series of steps called a reaction mechanism.
what is the rate determining step
The rate of reaction is dependent on the slowest step, which is called the ‘rate determining step’.
what can experimentally determined rate equations used to determine
Experimentally determined rate equations can be used to determine possible reaction mechanisms.
