OKIE LONG SINCE I TOUCHED KINETICS LET ME TRY DERIVIN DAT.........
d[a]/dt = [a]n....
d[a]/[a]n = dt ....
let half life be at t = T .... THUS [a] will become [a]/2 .............
[a]1-n[1/21-n-1] = T ......... for n > 1 ....
(n-1)ln2 = T ....... n=1 ..
sorry guys i waz just doin my revision online [3]
