Nitric oxide reacts with bromine gas at elevated temperatures according to the equation,

2 NO(g) + Br2(g) = 2 NOBr(g)

The experimental rate law is rate = k[NO][Br2]. In a certain reaction mixture the rate of formation of NOBr(g) was found to be 4.50 x 10-4 mol L-l s-l. What is the rate of consumption of Br2(g), also in mol L-l s-l?

a. 4.50 x 10-4 mol L-l s-l b. 2.25 X 10-4 mol L-l s-l c. 9.00 X 10-4 mol L-l s-l
d. 2.12 x 10-4 mol L-l s-l e. 2.03 x 10-3 mol L-l s-l
