Question
![Nitrosyl bromide decomposes by the reaction 2 NOBr(g) → 2 NO(g) + Br₂(g). Show that the following data are consistent with a second-order reaction and determine the second-order rate constant for the reaction.
Students may do this by plotting the data three different ways.
For each plot, time goes on the x-axis.
A zero-order reaction is linear when [NOBr] on the y-axis.
A first-order reaction is linear when In [NOBr] is on the y-axis.
A second-order reaction is linear when 1/[NOBr] is on the y-axis.
