Question: 4 examination of figure 25 shows that nin is greater...

Question details

4. Examination of Figure 2.5 shows that N.IN is greater fori 40 at p 0.97 than at either p=0.95 or p 0.99. This is generally true: various i-mers go through a maximum in numerical abundance as p increases. Show that the extent of reaction at which this maximunm occurs varies with i as follows: Pmax-(i -1/i. For a catalyzed AB reaction, extend this cxpression to give a function for the time required for an i-mer to reach its maximum numerical abundance.
