For the following reaction NO(g)  +  O2(g) –> NO2(g) a) What is the rate constant for this reaction if when [NO] = 0.75 M and [O2] = 2.2 M the rate of the reaction is 2.1 x 10-5 M/s.  Assume it is second order with respect to oxygen and first order with respect to nitrogen monoxide. b) using that constant, what is the concentration of oxygen needed to achieve a rate of 1.5 x 10-3 if the [NO] = 0.95M?
