During a wintertime inversion, the mixing height of an urban area is 0.143 km and winds are calm. Estimate the rise in CO levels during the morning commute, if 8000 vehicles all travel 1 km/km? of urban area, Assume: • Autos travel 10 km/kg of fuel and combustion products average 1% CO by weight • Use octane (cyclo-octane; CgH16) to represent the complex hydrocarbon mixture in gasoline with the following reaction: CaH16+ 1202 + 8CO, + 8H20 + some CO Answer will be in kg Co/km3, but do not include units. Round to the nearest hundredths place - ie. 0.089 rounds to 0.09.
