t-Butyl alcohol (TBA) is an important octane enhancer that is used to replace lead additives in gasoline. TBA was produced by the liquid-phase hydration (W) of isobutene (I) over an Amberlyst-15 catalyst. The system is normally a multiphase mixture of hydrocarbon, water, and solid catalysts. The use of cosolvents or excess TBA can improve miscibility. The reaction mechanism is believed to be: K, = k,/k- W +S = W S Kw = kw/k-w W.S+1.S= TBA S+S Ke = kror/krev %3D TBA S= TBA + S KTBA = 1/KTBAD =k-TBA/KTBA Derive a rate law assuming: a) the surface reaction is rate-limiting. b) the adsorption of isobutene is limiting.

Estimate the [03]/[O] ratio in Chapman mechanism at 30 km with p = 10 Torr, T = 250 K, using the J values and rate constants given. Hint: The mixing ratio of O2 is 0.21, which means [0₂] = 0.21 [M].

It is therefore useful to define a" family" of odd oxygen species: 0x = 0+03 The partitioning between O and O3 is set by reactions 2 and 3 (steady-state): k₂[0][0₂][M] =J03 [03]/ [O]/[03] = J03/(k₂[0₂][M]) The timescale for establishing this steady-state is quite fast: Even at 50 km, k₂[0₂][M] is = 0.05 s1.

In a batch reactor, reactant A is steadily converted into product B. The initialconcentration of reactant A is 100 mg/L. During a 10-hour reaction course, it wasobserved that the concentration of A in the reactor decreased at a constant rate of 10mg/L per hour. Based on the result, you can determine that the transformation reactionA→B follows ( ) with respect to reactant A.
