### Decomposition of NOBr **Be sure to answer all parts.** The decomposition of NOBr is studied manometrically because the number of moles of gas changes; it cannot be studied colorimetrically because both NOBr and Br\(_2\) are reddish-brown. \[ 2 \text{NOBr}(g) \rightarrow 2 \text{NO}(g) + \text{Br}_2(g) \] #### 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 | 0.0100 | | 2.00 | 0.0071 | | 4.00 | 0.0055 | | 6.00 | 0.0045 | | 8.00 | 0.0038 | | 10.00 | 0.0033 | The rates of decomposition of NOBr are: **(a)** \( 0.00067 \, \text{mol} \, \text{L}^{-1} \, \text{s}^{-1} \) ✅ **(b)** \( \_ \, \text{mol} \, \text{L}^{-1} \, \text{s}^{-1} \) ❌
