Chemical Kinetics Flashcards
arrhenius equation
k=Ae^-Ea/RT
how do we find the temperature from the arrhenius equation
T2= [1/T1- Rln(K2/K1)/Ea]-1
on what order reaction does the change in the concentration of the inital reactant affect the reaction?
Every reaction except Zero order
define rate law
It is an equation that tells us how the rate of reaction depends on the concentration of the reactants at a particular moment
define zero order reaction
It is a reaction that does not depend on the concentration of the reactants
define rate law
It is an equation that tells us how the rate of reaction depends on the concentration of the reactants at a particular moment
write the rate law expression
rate= k[A]^x[B]^y
is the order of the reaction necessarily the same as the stoichiometric coefficients in the balanced equation?
no
write the integrated rate law for the zero order reaction.
[A] t =−kt +[A]
define the first order reaction
it is a reaction where the rate of reaction depends on the concentration of reactants by a power of one
write the integrated rate equation for the first order reaction
ln [A]final=-kt+ln[A]initial
what is chemical kinetics
it is the area of chemistry that studies how fast a reaction goes or in other words the rate reaction
what is the rate of reaction?
It is the change in concentration of the reactant or a product over a given period of time
what is the unit of rate of reaction?
mol L–1 s–1
list factors affecting the rate of reaction
nature of reactants
concentation of reactants
surface area
