2. And just because it's an interesting bit of trivia...A number of my former students have gone on to take the MCAT and then have gone on to medical schools. All of them have commented on how the content of this class was a major part of the MCAT exam. We've talked a bit about how you are learning in this class versus a more traditional approach in teaching chemistry. Assuming that the loss of ability to recall Chem 401 material is a first-order process with a half-life of 52 days for the traditional (talking head lecture) and a half life of 295 days for the more interactive approach, calculate the number of days required to forget 90% of the material learned by each method. Assume a constant temperature and no further reference to the learned material during the decay time. (4 pts)Explanation / Answer
Case 1
No of days to forget 90% = t
For a first order process t = - (t1/2/ln 2) ln (10/100) = = - (52/0.693)x -2.303 = 172.8 days
Case 2
T = - (295/0.693)x -2.303 = 980.35 days
