- (a) The heat evolved upon dissolution of atmospheric ozone into water is determined to be +5 kcal/mol at 298 K. Given that ozone has a Henry’s constant of 9.4 × 10−3 mol/L/atm at 298 K, determine its Henry’s constant at 273 K. Note that the definition of Henry’s constant is for the process air to water. (b) If the atmospheric ozone concentration in a polluted air is 100 ppbv, what is the concentration in equilibrium with a body of water in that region at 298 K? Note that you need to assume no losses of ozone other than absorption into water- The major objective of a roasting process is to eliminate the Sulphur contained in the concentrate andto provide a calcine. In a roasting plant, 1000 kg per hour of molybdenum(IV) sulphide (MoS2) is roastedwith 25 % excess air to obtain MoO3 calcine in a chamber-type roasting furnace. Preheated air entersthe reactor at 400 K while MoS2 enters at room temperature. After the process, the waste gases leavethe reactor at 1000 K, and the calcine leaves at 850 K.a) Draw process flowsheet and heat balance diagram (ref. temp is 298 K) b) Calculate the amount of off-gas per hour in moles. c) Calculate the amount of calcined MoO3 per hour in kg.A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 9.0 mole% methane in air flowing at a rate of 7:00 x 102 kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. Calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (Note: Air may be taken to consist of 21 mole% O2 and 79% N2 and to have an average molecular weight of 29.0.)

After the liquid was heated to 96.7 oC the gass volatilized and the weight of the flask measure 227.33g. What is the could be the MW of the volatile sample?Meztiza, a beer cocktail, is prepared by mixing rum, beer, and cola. Compute the finalconcentration(%w/v) of ethanol in meztiza if 100.0 mL of beer was first mixed with 5.0 mL rum andbefore finally diluting it with cola to produce 200.0 mL of the beer cocktail. ( a beer contains about 4.50% (v/v) of ethanolfermented by yeast from sugars while rum contains about 40.0% (v/v) ethanol. Meanwhile, arubbing alcohol is also an alcohol solution which contains 70.0 %(v/v) isopropyl alcohol fermentedby a bacterium instead of a yeast)
- For the equilibrium system: H2O(g) + CO(g) <--> H2(g) + CO2(g). Delta heat of rxn: -42 kJ/mol and Kc=0.62 at 1260 K.0.10 mol each of water, CO, and CO2 (all at 1260 K) are placed in a sealed 1.0-Liter thermally-insulated vessel, which is also at 1260 K. When the system comes to equilibrium, which is true?-The temp & mass of CO would increase.-The temp & mass of CO would decrease.-The temp would remain constant & the mass of CO would increase.-The temp would increase and the mass of CO would decrease.-The temp would decrease and the mass of CO would increase.Kindly provide the Process Flow Diagram, Basis, Find, Show Complete Step by Step Solution Topic: Material Balance on Single Unit with Reaction(II) A 1.0-L volume of air initially at 3.5 atm of (gauge)pressure is allowed to expand isothermally until the pressureis 1.0 atm.
