Calculate the pH of a mixture of 0.25 M acetic acid and 0.1 M sodium acetate. pKa of acetic acid is 4.76. What is the pH in the preceding problem if the mixture consists of 0.1 M acetic acid anc 0.25 M sodium acetate?

Ethylene gas is converted ethanol compound by vapor phase hydration reaction. is being transformed. Maximum conversion amount at 523 K and 35 bar conditions, Calculate based on the amount of steam being 5 times the amount of ethylene. gas in equilibrium Assume that the mixture exhibits ideal solution behavior.

Draw a Pxy diagram for an aqueous solution of NH3. The temperature is such that the vapor pressure of the pure water is 5 kPa and the vapor pressure of pure NH3 is 600 Pa. You need to include the bubble line and the dew 7. line. (a) What is the vapor pressure of the solution when rNH, = 0.6? (b) In which phase the solution will be at P = 4.8 kPa? (c) In which phase the solution will be at P =0.2 kPa? (d) Draw the path for a process that takes a liquid with INH, = 0.6 %3D and P= 4.8 kPa to P= 0.2 kPa.

Unable how to proceed with a partial pressure problem (For Practice), if anyone could shed light on how to proceed! Thank you so much, I greatily appreciate the help

How did you assume the coefficient of discharge Cd? Did you get it from a table?    Thx

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.

The vapor pressure curve for phosphorus oxychloride (POC13) is described by the following equation Pvap = 0.0003 T³ +0.0136 T² +0.3702 T+7.2708 Pvap. (mmHg), T (Kelvin) 1. Find Pvap, in the temperature range -30 °C to 60 °C using 10 °C increments. 2. Using the Charting guidelines, draw the curve of Pvap. vs. T (K). Hints: 1- Construct a table like the following on Excel: T(°C) T (Kelvin) Pvap.(mmHg) -30 243 -20 -10 2- Exponent (power) function in Excel formula is (^). 3- Proper labeling of chart title, axes The solubility of Oxygen gas (O2(g)) in water in units of (g 0₂/100 g H₂O) is described by the following equation: Solubility=-1×10 T³ +2×10 T²-2×10 T +0.0069 (a) Using the Charting guidelines, Plot the solubility of O2(g) in water as a function of temperature over the range 0-100 °C using 5 °C increments. (b) What is the effect of increasing temperature on the solubility of O2(g). Note: "A" as a function of "B" OR "A" vs. "B" → "A" is the y-variable and "B" is the x-variable

This graph shows how the vapor pressure of three liquids varies with temperature: 900 800 700 600 500+ 400 300 I - methanol 200 acetone 100 trichloroethylene 50 60 70 80 90 temperature, °C Use the graph to answer the following questions: most volatile: acetone Which liquid is the most volatile? Which is the least volatile? least volatile: trichloroethylene v methanol: What is the normal boiling point of each liquid? Note: your answer must be within 1°C of the exact answer to be graded correct. acetone: trichloroethylene: more Suppose a beaker of acetone is put inside a sealed tank containing acetone gas at 54. degree C and 709. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same amount? O less the same ? vapor pressure, torr
