A flask is charged with 0.100 mol of A and allowed to react to from B according to the hypothetical gas-phase reaction A(g) --†’ B(g). The following are collected:

(a) Calculate the number of moles of B at each time in the table, assuming that A is cleanly converted to B with no intermediates.
(b) Calculate the average rate of disappearance of A for each 40-s interval in units of mol/s.
(c) What additional information would be needed to calculate the rate in units of concentration per time?
