Bonus: a). [4 points] Methanol is formed from carbon monoxide and hydrogen in the gas phase reaction: CO + 2H2 \leftrightarrow CH3OH. For simplicity, let the reaction be A + 2B \leftrightarrow C The equilibrium constant at temperature T, K(T), expressed in terms of the mole fractions of the reactive species and the total pressure is given by K(T) = y_c / \{(y_A \cdot y_B^2)P^2\} Suppose the initial feed to the reactor contained 1 mole A, 1 mole B, and no C, write expressions for the moles (n_A, n_B, n_C) and mole fractions (y_A, y_B, and y_C) of each species in terms of the extent of reaction \epsilon at equilibrium. Then, express the equilibrium constant K(T) in terms of only \epsilon and P.

In an object-oriented college simulation system, we have the following classes. Draw an inheritance diagram that you feel shows the relationships between these classes. • Student • Professor • Course • Person • Lecture • Employee • Person • Janitor • Secretary • Teaching Assistant (TA) You have the HTML editor at your disposal to use; however, you may also draw a simple diagram as long as your "arrows" and relationships are clear. For example: Vehicle | Car Bicycle Truck | Coup Sedan

7.5. Weak acid vs strong base & 7.6. Weak base vs strong acid Comparison: 12.0 Observations: $K_a = 10^{-10}$ 10.0 $K_a = 10^{-8}$ 8.0 A. pH at the equivalence point decreases with $K_a$. $K_a = 10^{-6}$ 6.0 B. Starting pH decreases with $K_a$. $K_a = 10^{-4}$ 4.0 C. Change in pH near the equivalence point $K_a = 10^{-2}$ 2.0 becomes steeper with $K_a$. 0 Strong acid 10 20 30 40 50 60 Vol 0.10 M NaOH added (mL) $pH = pK_a + log\frac{[A^-]}{[HA]}$ $[H^+] = [OH^-]$ $HA \rightleftharpoons H^+ + A^-$ Questions: • A. Why you have double changes for the titration curves with small $K_a$? B. Can you predict pH at the position of a half way to the equivalence point (30/mL NaOH addi in this case)? 25mL End of chapter
