A non-steroidal anti-inflammatory drug is metabolized with a first-order rate constant of 3.25 day−1 . what is the half-life for the metabolism reaction? 1. 1.63 day 2. 0.308 day 3. 0.213 day 4. 2.25 day

Respuesta :


A radioactive half-life talks about the amount of time it takes for half of the original isotope to deteriorate.

The solution for this problem is:

Half-life (lst order reaction) = ln2 over k 

so half-life = .693 over 3.25 = .213 day is the half-life for the metabolism reaction
