Unformatted text preview: necessarily to scale) for NH 3 . It useful to think of plotting Log P (yaxis) versus T (xaxis). Indicate a point in the phase diagram for the following conditions. For each point, state which and how many phases are present. a) 195.41 K, 1050 Pa b) 195.41 K, 6077 Pa c) 237.51 K, 101325 Pa d) 420 K, 130 × 10 5 Pa e) 190 K, 6077 Pa 3. a) Use the phase rule to determine f for an aqueous solution of HCl in equilibrium with its vapor. What would appropriate independent variables be to characterize the system? b) Use the phase rule to determine f for an aqueous solution of HCl and HI in equilibrium with its vapor. What would appropriate independent variables be to characterize the system? 4. Consider aqueous H 2 SO 4 . It and the water can ionize to form H + , OH – , HSO 4 – and SO 4 2– . What is f ? What would appropriate independent variables be to characterize the system?...
