Deriving the functions of graphs Half life
1
Q
What is function of a first order graph?
A
[R] = [R]o - kt
2
Q
function of 2nd order graph
A
1/[R] = 1/[R]o + kt
3
Q
function of 3rd order graph
A
1/[R]^2
4
Q
half life for 1st order
A
use 1st order graph function, but make it = to 1/2; then ln both sides, etc… thus = ln2/k
5
Q
half life of 2nd order
A
t1/2 = 1/([R]o * k)
