The decomposition of nobr is studied manometrically because the number of moles of gas changes; it cannot be studied colorimetrically because both nobr and br2 are reddish-brown. 2nobr(g) →2no(g) + br2(g) use the data below to make the following determinations: (a) the average rate of decomposition of nobr over the entire experiment. (b) the average rate of decomposition of nobr between 2.00 and 4.00 seconds. time (s) [nobr] (mol/l)0.00 0.01002.00 0.00714.00 0.00556.00 0.00458.00 0.003810.00 0.0033the rates of decomposition of nobr are
