Order of reaction if half life is inversely proportional to initial concentration

5 Answers

hmm...
general case...

nth order's half life is proportional to a^1-n

so now u say ... wat it shud be...

second order

yup it is :)

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[1/2^1-n-1] = T ......... for n > 1 ....

(n-1)ln2 = T ....... n=1 ..

sorry guys i waz just doin my revision online [3]
