(c) Kinetics

What does the rate of the reaction normally depend on

the concentrations of the reactants

What are orders of reaction used for

used to relate the rate of a reaction to the reacting species

What happens if changing the concentration of a reactant A has no effect on the rate of the reaction

then the reaction is zero order with respect to A

What happens if doubling the concentration of a reactant A doubles the rate of the reaction

then the reaction is first order with respect to A

What happens if doubling the concentration of a reactant A increases the rate of the reaction fourfold

then the reaction is second order with respect to A

What is the overall order of a reaction

the sum of the powers to which the concentrations of the reactants are raised in the rate equation

What can the order of a reaction only be determined from

experimental data

What are the series of steps in a reaction called

a reaction mechanism

What is the rate determining step

the slowest step in the rate of reaction

What can experimentally determined rate equations be used to determine

possible reaction mechanisms

What is the order of a reaction definition

Is the number of moles/molecules of reactants involved in the rate determining step (slowest step)
