Awaste gas contains 0.1 mol% toluene in air and occupies a volume of 2,120 m3 at 298 k and 116 kpa. in an effort to reduce the toluene content of this gas, it is exposed to 113 kg of activated carbon, initially free of toluene. the system is allowed to reach equilibrium at constant temperature and pressure. assuming that the air does not adsorb on the carbon, calculate (a) the equilibrium mole fraction of toluene in the gaseous phase and (b)the amount of toluene adsorbed by the carbon. the adsorption equilibrium for this system is given by the freundlich isotherm: w = 0.208(p*)^0.11. in this equation w is the carbon equilibrium adsorptivity, in kg of toluene/kg of carbon, and p* is the equilibrium toluene partial pressure, in pa. (mw of toluene = 92)

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
