Method of Initial Rates |
when you get a table ratio the experiments (their rate laws) and set exponents to x and y to get the orders
as long as temp is constant
then you can stick it all back in and get rate |
|
|
Graphical Method |
Integrated rate laws if linear when axis is [ ] --> zero order if linear when axis is ln[ ] --> first order if linear when axis is 1/[ ] --> second order
slope (rise/run) is k |
|
|
Isolation Method |
for when there's more than 1 species |
|
|
Half Lives |
use ln eq'n for first order, can get k if use ln(2) aka .693 aka .693/k = t1/2 (for first orders, half life remain constant throughout) |
|
|
when do you use integrated rate law? |
how [ ] changes with time for zero order: [A]t = -kt + [A]o for first order: ln[A]t = -kt + ln[A]o for second order: 1/[A]t = kt + 1/[A]o
slopes still k i think |
