Solution:
Consider the gas-phase reaction between nitric oxide and bromine at 273 oC 2NO(g) + Br2(g)  →  2NOBr(g). The following data for the initial rate of appearance of NOBr were obtained:
Experiment [NO[Br2](M)Initial Rate of Appearance of  NOBr (M/s)   
10.100.2024
20.250.20150
30.100.5060
40.350.50735
What is the rate of disappearance of Br2 when [NO]= 7.1×10−2 M and [Br2 ]= 0.26 M ?
