Extracted text: 1. Find the breakthrough time (day) for 80-ppm vinyl chloride (C2H;CI) adsorption on activated alumina for a bed 3 m in height. The total gas flow rate is 8 m/min, the bed density is 480 kg/m', the bed cross sectional area is 1 m?, and the isotherm is given by a Freundlich model with k=0.86 and n=0.45. Neglect the mixing front depth. Assume T= 298 and P = 1 atm.
