The reaction NO2(g) + CO(g) → NO(g) + CO2(g) has been found to be second order with respect to NO2 and zero order with respect to CO. At a certain temperature, the rate constant is found experimentally to be 3.0 × 10−5 L mol · s . What is the rate of formation of CO2 at this temperature when the concentration of NO2 is 4.3 mol/L, that of CO is 6.9 mol/L, that of NO is 7.7 mol/L, and that of CO2 is 7.6 mol/L? Answer in units of M · s −1 .
