Question

The following mechanism has been proposed for the gas phase reaction of nitrogen monoxide with bromine.

.....step 1.....fast:......NO + Br_{2 <==>}  NOBr₂

.....step 2.....slow:....NOBr₂ + NO -->2 NOBr

(1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank.

_____ + ______ ----> __________

(2)

Enter the formula of any species that acts as a reaction intermediate? If none leave box blank:

__________

(3) Complete the rate law for the overall reaction that is consistent with this mechanism.
Use the form k[A]^m[B]ⁿ... , where '1' is understood (so don't write it if it's a '1') for m, n etc.

Rate = ________?
