Question

ASAP!!!!!!!!!! A simulated dishwashing activity was conducted in a room-sized test chamber (V = 20 m3). The concentration of ethanol (a component of dishwashing detergent) was measured during and after 20 minutes of dishwashing. The chamber was ventilated with ethanol-free air (rate = 0.7 m3 min-1). Assuming that ethanol is nonreactive, show how the total mass of ethanol emitted by the dishwashing can be determined from these data. Sealed box, single air pollutant, single (consumptive) chemical reaction. At an initial time, t = 0, the contaminant concentration is C0. We want to know the contaminant concentration. Ct, at some later time, t. Define characteristic time for the reaction is t. for time (t) < t, how will Ct and C0 compare? for t >> t, how will Ct and C0 compare?
