Assume that the formation of nitrogen dioxide2NO(g) + O2(g)2 NO2 (g)is an elementary reaction. A sample of air at a certain temperature is contaminated with 2.0 ppm of NO by volume. Under these conditions, the half-life of thereaction has been estimated to be 6.4 × 103 min. What would the half-life be if the initial concentration of NO were 14.0 ppm? Round your answer to 2significant digits.minX5
