2. Consider the P-x-y diagram at 300 K for A-B mixtures at right. (a) What are the vapor pressures of A and B at 300 K? (b) A 25 mol-% A vapor mixture is isother- mally compressed from 1.5 to 2.0 bar. Does a 2-phase mixture form, and if so, what is the mole fraction of A in each resulting phase? (c) Using data at the azeotrope, compute the van Laar parameters a and 3 for A-B mix- tures at this temperature. P (bar) 2.8 2.6 2.4 2.2 2.0 1.8 1.6 1.4 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 XA or YA

1. Draw the gas absorption tower with N = 10 (similar to the figure below, but you should draw your own; instead of n or N, you should have actual numbers). Label EACH AND EVERY liquid and vapor streams – flowrates and mole fractions with correct subscripts. 2. Write definitions for the following terms in your own words: V, y, L, x, L, x, V, y., VYNU n-1⁹ n-19 Xa I V₂ Y₂ = YN+1 V₁ = V₁ Ya = y1 Ln-1 Xn-1 Yn Ln Xn +Plate 1 Plate n- Plate n Vn+1 Yn+1 Plate n + 1 Plate N = LN Xb = XN

Q3. The following information on the pressure-temperature diagram of nitrogen: P (atm) T(K) 0.123 33.3978 1.0 Triple point Critical point Normal boiling point Density of N₂(s): 1.03g/cm-³ N₂(1): 0.808g/cm-³ 63.15 126.19 77.35 Using this information, sketch a phase-equilibrium diagram of nitrogen and mark each point. Then, describe why the slope of each phase/phase equilibrium is positive or negative.

3. Fig. 3-1 shows z as function of mole fraction of butane in a nitrogen/butane mixture. The figure shows line for various pressures. Explain why z for pure butane behaves so differently from z for pure nitrogen as P increases, in particular, why is the butane z non-monotonic in pressure.

Complete the property table for water below. Use only the Thermodynamic Property Table for Water referring to the Smith, Van Ness and Abbot Thermodynamics textbook. P [kPa] V [m³/kg] H[ kJ/kg] T[°C] Phase Description X 500 Saturated liquid 171 2044.5 300 0.8 Note that x refers to the "quality" or the mass fraction of the water in vapor phase. If the system is composed of pure liquid water, x = 0. If the system is composed of pure gaseous steam, x = 1. The volume of a liquid/vapor system can be determined using the following equation. V = Vj + x(Vg-Vj) V - volume of saturated liquid water Va - volume of saturated gaseous steam Similar calculation can be done for other properties such as internal energy, entropy, and enthalpy. H = HỊ + x(Hg-H) Under phase description, indicate whether the system is composed of saturated liquid, saturated vapor, superheated vapor, or liquid-vapor mixture. Also note that when pressure is given, it is more advisable to use the Superheated Steam Table than…
