3) (35 pts) Consider the heterogeneous gas phase dehydrogenation of isopropanol to acetone using a solid Cu-SiO$_2$ catalyst. $(CH_3)_2CH(OH) \rightleftharpoons (CH_3)_2C=O + H_2 + H$ I A The reaction has the following rate equation. $-r_1 = k_f \left[ C_I - \frac{C_A C_H}{K_{eq}} \right]$ The following questions refer to reaction conditions of 300 $^\circ$C and 10 atm, where $k_f$ is 0.0715 $\frac{L}{g_{cath}}$ and $K_{eq}$ is 0.274 $\frac{mol}{L}$. A) (3 pts) Write the stoichiometric table in terms of the fractional conversion of isopropanol. B) (9 pts) Find the equilibrium fractional conversion. C) (4 pts) You need to size an ideal, isothermal packed bed reactor to produce 100 million lb/yr of acetone. What molar feed rate of isopropanol (in mol/h) is required to achieve 60% conversion of isopropanol? D) (19 pts) Calculate the mass of catalyst that will be required to achieve 60% conversion of isopropanol. Assume that the ideal gas law applies and that the feed is pure isopropanol.

2. In a herd of 1000 cows, each with one calf, weaning weight was recorded as a selection criterion. The mean values for bull and heifer calves were 300 Kg and 250 Kg respectively, and the standard deviation was $\sigma_p = 50Kg$ in each sex. a) What would you expect to be the weight of the heaviest bull (Hint: first determine the proportion selected for one bull, then use the corresponding selection intensity in determining your answer)? b) If $h^2 = 0.30$, what is the estimated breeding value of this best bull? c) If he were mated to a randomly selected group of heifers, what would be the expected progeny mean? Assume an equal expression of response in each sex, and an equal sex ratio (50:50). d) If he were mated to all the heifers of 250Kg and over, what would be the expected progeny mean? (Hint: For a given proportion selected the appendix table does not only contain selection intensity $i$ (average value of selected fraction), but also truncation point $x$ (lowest value of selected fraction).
