A chemical plant produces an ammonia-rich waste gas that cannot be released as-is into the environment. One method to reduce the ammonia concentration in the waste gas is to bubble the waste gas through a liquid solvent. Components of the gas that are highly soluble, like ammonia, will dissolve into the liquid phase. Water is an appropriate liquid solvent for this process. The chemical plant produces 125.0 m3/hr of waste gas (? = 0.0407 mol/L) initially having a mole fraction of 0.180 NH3, and wishes to remove 90.0% of the initial amount of NH3. The maximum concentration of ammonia in water at this temperature is 0.5000 mol NH3/ mol water. Neglect the absorption of other waste gas components into the water, and the evaporation of water into the waste gas stream.
What rate is nh3 being removed from the feed gas? (in mol/hr)
What is the minimum flow rate of water (? = 0.990 g/mL) required to scrub out 90.0% of the incoming NH3? (in L/hr)
What is the mole fraction of NH3 in the scrubbed waste gas stream? (in mol nh3/mol waste gas)
A 10g sample of acetic acid HC2H3O2. was burned in a bomb calorimeter in an excess of oxygen. The temperature of the calorimeter rose from 25 C to 35.84C. If the heat capacity of the calorimeter and its contents is 13.43KJ/C, what is the enthalpy ..
