![Problem 10 For a 2 step consecutive reaction: k: The concentration of B, [B], as a function of time was derived to be: [B] = (k2-k1) a. Show that the time when the maximum value of [B] occurs is: tmax = (ka-ki) Ln (k2 b. If ki = 0.100 s., and k2 = 0.0500 s., how much time (in s) does it take for [B] to reach its maximum value?](http://img.homeworklib.com/questions/dba4fc40-b6c1-11ec-808c-bbd4c69002e6.png?x-oss-process=image/resize,w_560)

Problem 2. Consider n flips of a coin. A run is a sequence of consecutive tosses with the same result. For k<n, let Ek be the event that a run is completed at time k; this means that the results of the kth and (k1)st flips are different. For example, if 10 and the outcomes of the first 10 flips are HHHTTHHTTH then runs are completed at times 3,5,7,9 (a) Show that if the coin is fair, then the events...
