1) Time(min) 0 10 20 30 40

Moles of A 0.065 0.051 0.042 0.036 0.031

- Calculate the number of moles of B at each time in the table, assuming that there are no molecules of B at time B at time zero, and that A cleanly converts to B with no intermediates.

- Calculate the average rate of disapperance of A for each 10-min interval in units of M/s.

- 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.
