2. (a) Predict the intrinsic rate of reaction for the oxidation of SO2 at bulk gas condition of 20% conversion at 480C (20%). A feed consisting of 6.5 mol % SO2 and 93.5 mol % air has the global rate to be 0.0898 (g mol SO) / ((h)(g cat.)) with the superficial mass velocity to be 350 lb / ((h)(ft2)). Other conditions are as given in Example 10-1 & 10-2. The intrinsic rate at the catalytic surface is to be calculated from Eqs. (G) and (H) of Example 9-2. Assume isothermal conditions, the constants in Eqs. (G) and (H) at 480C are A = -0.127((atm) 3/2/( g mol / ((h)(g cat.))))/2; B = 15.3 ((atm)-1/2/(g mol / ((h) (g cat.))))2; K= 73 (atm)-1/2. Schmidt numbers for SO2, O2, and SO3 are 1.21, 0.81 and 1.34, respectively. Also, (b) calculate the ratio y of the intrinsic rate from (a) and the rate evaluated at bulk conditions from Eqs. (G) and (H) of Example 9-2 (5%). 2. (a) Predict the intrinsic rate of reaction for the oxidation of SO2 at bulk gas condition of 20% conversion at 480C (20%).
