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.
