It is intended to produce Propylene Glycol, PG (CH₂(OH)CH(OH)CH3) by the hydrolysis of Propylene Oxide, PO (CH₂OCHCH3) in CSTR. The acid-catalyzed liquid-phase exothermic reaction is shown below: CH₂OCHCH₂ + H₂O CH₂(OH)CH(OH)CH₂ The feed, containing 3 mol/L of Propylene Oxide and 30 mol/L of water, enters the well-mixed adiabatic reactor at 303 K at a total volumetric flowrate of 10 L/min. Propylene Oxide is a volatile substance, and you cannot exceed an operating temperature of 80°C. Assume that you operate the system at this maximum temperature. Additional Information: AHxn(298K) = -18,000 cal/mol k at 298 K = 2.77x10 min¹ Gas law constant = 1.987 cal/K.mol. E = 15,000 cal/mol Cp (PO) 35 cal/molk = Cp (H20) 18 cal/mol K Cp (PG) = 46 cal/mol K The reaction is dependent in Propylene Oxide concentration and independent of water concentration. It can be treated as a first order and also second order reaction. Analyse and justify the effect of reaction order on the conversion of reaction and volume of reactor.

Hydroxyapatite, Ca10(PO4)6(OH)2 , has a solubility constant of Ksp = 2.34×10−59, and dissociates according to Ca10(PO4)6(OH)2(s)↽−−⇀ 10Ca2+ (aq) + 6PO3−4 (aq) + 2OH− (aq) Solid hydroxyapatite is dissolved in water to form a saturated solution. What is the concentration of Ca2+ in this solution if [OH−] is fixed at 9.60×10−4 M ?
A highly acidic (pH< 0.5) industrial wastewater has an initial AlP" concentration of 10 ppm. An engineer decides that strong base should be added to the wastewater in order to raise the pH so that most of the aluminum will precipitate and be removed from solution. The pertinent solubility reaction from Appendix A of our text is: Al(OH)3 (s) → Al* + 30H¯ with pK, = 32.9 a. What is the lowest pH needed to precipitate all but 50 ppb of the aluminum from the wastewater? Assume equilibrium conditions can be achieved. b. Suppose the engineer decides that the pH should be raised to 7. What equilibrium concentration of aluminum would be left in solution? Report your answer in ppb and moles per liter.
4. Open bodies of water can act as carbon sinks due to the ability of carbon dioxide to dissolve in water. The dissolution of carbon dioxide produces carbonic acid (H₂CO3) which then partially dissociates in an equilibrium reaction important for controlling water pH. CO₂ (g) + H₂O (1)→ H₂CO3(aq) H₂CO3 (aq) H+ (aq) + HCO3(aq) The equilibrium between carbonic acid (H₂CO3) and bicarbonate (HCO3) is influenced by the presence of dissolved metals from the bedrock underlying a body of water. Calcium from limestone (a type of sedimentary rock formed from marine exoskeletons) is one such metal. The graph below shows how the concentration of dissolved calcium ions (measured in parts per million, or mg/L) affects the concentration of carbon dioxide dissolved in ocean water (measured partial pressure). Based on this graph and your understanding of equilibrium, in what direction does the presence of limestone shift the carbonic acid/bicarbonate equilibrium? 10-4 10-3 Closed Calcite saturation-…
