2.3 kinetics Flashcards
what does the rate of a chemical reaction normally depend on
the concentration of the reactants
what are the orders of reaction used for
to relate the rate of a reaction to the reacting species
complete the sentence; if changing the concentration of reactant A has no effect on the rate of the reaction…
then the reaction is zero order with respect to A
when is a reaction zero order, with respect to A
if you changed the concentration of the reactant A but there was no effect on the rate of the reaction
complete the sentence; if doubling the concentration of a reactant A doubles the rate of the reaction…
the reaction is first order with respect to A
when is a reaction first order
when the doubling of a reactant doubles the rate of the reaction
what does rate =
k [A]
when is a reactant considered to be second order
if doubling the concentration quadruples the rate of the reaction
what does rate = in respect to second order
k [ A] ‘2
what is the order of a reaction
the power to which the concentration of that reactant is raised in the rate equation
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
how can the order of a reaction be determined
only from experimental data
what is the reaction mechanism
the series of steps that a reaction occurs by
what is another name for the slowest step
the rate determining step
what can experimentally determined rate equations be used to determine
possible reaction mechanisms
