Academics

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 over the entire experiment (b) the average rate between 2.00 and 4.00 s Time (s) [NOBr] (mol/L) 0.00- 0.0100 2.00- 0.0071 4.00- 0.0055 6.00- 0.0045 8.00- 0.0038 10.00- 0.0033
