The oxidation of SO2 is to be carried out over a solid platinum catalyst in a packed bed reactor. As with almost all gas-solid catalytic reactions, the rate law is expressed in terms of partial pressures instead of concentrations. The rate law is found experimentally to be: −rSO2 ′ = k ൤PSO2ඥPO2 − PSO2 Kp ൨ ൫1 + ඥPO2 KO2 + PSO2 KSO2 ൯ 2 , mo SO2 oxidized(h −1 )(g catayst) −1 Where Pi (atm) is the partial pressure of species i. the reaction is to be carried out isothermally at 400 °C. At this temperature, the rate constant k, the adsorption constants for O2 (KO2 ) and SO2 (KSO2 ), are the pressure equilibrium constant (Kp) where found experimentally to be: k = 9.7 mol SO2/atm3/2/h/g-cat, KO2 = 38.5 atm-1 , KSO2 = 42.5atm-1 O2 and Kp = 930 atm-1/2 The total pressure is 14.7 atm. The inlet is a mixture of 28% SO2 and 72% air by mol. There is no pressure drop. Using Polymath (or Matlab), plot Fao −ra vs. W, for W ranging from W = 0 to 1000 g.

Be sure to answer all parts. the catalytic destruction of ozone occurs via a two-step mechanism, where x can be any of several species: (1) x + o3 → xo + o2 [slow] (2) xo + o → x + o2 [fast] (a) write the overall reaction. o3 + o → 2 o2 o3 + xo → x + 2 o2 xo + x + o3 + o → xo + x + 2 o2 x + o3 → xo + o2 (b) write the rate law for each step (using k for the rate constant). reaction 1: reaction 2: k[x][o2] k[xo][o2] k[x][o3] k[xo][o3] k[xo][o2] k[x][o] k[x][o2] k[xo][o] (c) x acts as a and xo acts as a catalyst intermediate intermediate catalyst (d) high-flying aircraft release no into the stratosphere, which catalyzes this process. when o3 and no concentrations are 3 ă— 1012 molecule/cm3 and 9.9 ă— 109 molecule/cm3, respectively, what is the rate of o3 depletion? the rate constant k for the rate-determining step is 6 ă— 10â’15 (cm3)2/moleculeâ·s. give your answer in scientific notation. use one significant figure in your answer. ă— 10 molecule/s
