Answer #1

Solution:

Answer is False

Because a longer breakhrough time imply better adsorption capacity. This means it would take a longer time for your adsorbent material to completely saturated with the adsorbate. We have pollutant flow rate is 100 lb/h which is 10 times lesser than 10,000 lb of activated carbon adsorbent. So it takes long time more than 2 hours to complete the process. For packed bed breakhrough time is directly proportional to equilibrium adsorption capacity.

You have discovered a fabric which when it contains an adsorbent such as activated carbon can be used to make an overcoat that can protect you from toxic chemicals. In a test of such fabric, a gas stream containing 8.0 mg/L of carbon tetrachloride (CCl4) was passed through 7.71 g sample of the fabric at a rate of 1 L/min and the concentration of CCl4 in the gas leaving the fabric was monitored. The run was continued for 15 min...
