Consider the following hypothetical aqueous reaction: A(aq) → B(aq). A flask is charged with 0.065 mol of A in a total volume of 100.0 mL. The following data are collected
| Time (min) |
0 |
10 |
20 |
30 |
40 |
| Moles of A |
0.065 |
0.051 |
0.042 |
0.036 |
0.031 |
(a) Calculate the number of moles of B at each time in the table, assuming that there are no molecules of B at time zero, and that A cleanly converts to B with no intermediates.
(b) Calculate the average rate of disappearance of A for each 10-min interval in units of M/s?
(c) Between t = 10 min and t = 30 min, what is the average rate of appearance of B in units of M/s? Assume that the volume of the solution is constant.
