Question: 3.A temporary bus stop was located next to the air intake for a lecture hall. The air flows through a 1 meter wide, square duct

3.A temporary bus stop was located next to the air intake for a lecture hall. The air flows through a 1 meter wide, square duct directly from the intake to the lecture hall, a distance of 500 meters. The constant idling of buses has created a CO concentration of 1000mg/m outside. If the air flows through the ducts with a velocity of 0.4m/s, and the CO reacts to form CO2 with a first order rate constant k = 0.7min-, what is the concentration of CO in the air entering the classroom?

3. (2 points) A temporary bus stop was located next to the air intake for a lecture hall. The air flows through a 1 meter wide, square duct directly from the intake to the lecture hall, a distance of 500 meters. The constant idling of buses has created a CO concentration of 1000mg/m3 outside. If the air flows through the ducts with a velocity of 0.4m/s, and the CO reacts to form CO2 with a first order rate constant k=0.7min1, what is the concentration of CO in the air entering the classroom
