Question
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:
(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.
