In a 30 m' room, a stove in operation consumes wood at the rate of 0.25 kg/h. The inflow and outflow rate of air in the room is the same, i.e. 500 m³/h. This stove emits a VOC species at a rate of 0.2 g/kg-wood. The VOC species gets converted to CO₂ at a rate of 0.4 per hour. Given: (i) the air in the room is completely mixed, (ii) initial concentration of the VOC species in the room is negligible, and (iii) concentration of the VOC species in the air entering the room is negligible. The concentration of the VOC species due to two hours of stove operation in the room (in ug/m³, rounded off to one decimal place). is In a 30 m' room, a stove in operation consumes wood at the rate of 0.25 kg/h.
