A flask is charged with0.130mol of A and allowed to react to form B according to the following hypothetical gas-phase reaction.
The following data are collected.
|moles of A||0.130||0.070||0.044||0.030||0.025|
(a) Calculate the number of moles of B at each time in the table.
(b) Calculate the average rate of disappearance of A for each 40 s interval, in units of mol/s.
0 – 40 s
40 – 80 s
80 – 120 s
120 – 160 mol/s
