Question
flask is charged with 0.100 mol of A and allowed to react to form B according to
the following hypothetical gas - phase reaction. A(g) B(g) The following data are
collected. times (s) 0 40 80 120 160 moles of A 0.100 0.065 0.042 0.030 0.023 (a)
Calculate the number of moles of B at each time in the table. 0 s mol 40 s mol 80 s
mol 120 s mol 160 s mol (b) Calculate the average rate of disappearance of A for
each 40 s interval, in units of mol/s. 0-40 s mol/s 40 - 80 s mol/s 80 - 120 s
mol/s 120 - 160 mol/s mol/s
