describe second order recations
two components in rate equation. rate = k2{a][b]
1 of 15
what assumption is made,what is equation
that [a]=[b]. -d[a]/dt=k2[a]squared
2 of 15
what is the linear equation
1/[a]t=k2t + 1/[a]0
3 of 15
what is the half life equation
1/k2[a]0=t1/2
4 of 15
what happens if second order reaction is put in 1st order linear equation
a curve will still be produced
5 of 15
describe zero order reactions
rate is indepedant of reactant concentration
6 of 15
what is rate equation
-d[a]/dt=k
7 of 15
what is linear equation
[a]t=[a]0-kt
8 of 15
what is half life equation
t1/2= [a]0/2k
9 of 15
zero vs first order?
zero looks like first but when put in log equation it gives a curve
10 of 15
effects of tempeture on rate
increased temp increases collison rate so increases collison with the correct orientation so rate increases
11 of 15
temps effect on k? what equation to measure
increased temp increases k. arrhenius equation
12 of 15
what effect does a high ea have on k
k decreases
13 of 15
what is arrhenius equation
k=Aeto the power of -Ea/RT
14 of 15
what is linear arrhenius
logk= (-ea/R)(1/T) + log a
