A bar of volume V has N smokers in it, each smoking m cigarettes per hour. Cigarettes emit several substances, including the carcinogen formaldehyde. Each cigarette generates qgmg/m3. Formaldehyde converts to carbon dioxide at a reaction rate of k. Fresh air with a background concentration Ci of formaldehyde enters the bar at a volumetric flow rate Q and polluted air leaves the bar at the same rate. 1 point What is the generation rate of formaldehyde in the bar? G=mN/qgG=mNqgG=N/mqgG=m/Nqg 1 point What is the steady state concentration of formaldehyde in the bar?
