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 ln[NOBr] is on the y-axis. A second-order reaction is linear when 1/[NOBr] is on the y-axis. t 0 5 10 15 50 85 s [NOBr] 0.0653 0.0514 0.0424 0.0361 0.0177 0.0117 M What is the rate law for the reaction? (Rate equations take the general form 'rate = k . [A] . [B]'.) chemPadHelp rate = k. [NOBr]2 rate = k. [NOBr]^2 Correct. What is the value of the rate constant at the temperature of the experiment? WebAssign will check your answer for the correct number of significant figures. 0.830 Incorrect: Your answer is incorrect.

The exception to an octet of electrons would be the first noble gas, Helium, which only has two valence electrons. This primary affects the element hydrogen, which forms stable compounds by achieving two valence electrons.
