- The emission of NO, by fossil fuel combustion can be prevented by injecting gaseous urea into the combustion mixture. The urea reduces NO (which oxidizes in air to form NO2) according to the reaction: 2 CO(NH;)»(3) + 4 NO(3) + O2(8) 4 Na(8) + 2 CO;(g) + 4 H¿O(g) Suppose that the exhaust stream of an automobile has a flow rate of 2.55 L/s at 655 Kand contains a partial pressure of NO of 12.4 torr. What total mass of urea is necessary to react complete- ly with the NO formed during 8.0 hours of driving?A chemical manufacturer produces ethylene oxide by burning ethylene gas with air in the presence of catalyst. If the conditions are carefully controlled, a substantial fraction of ethylene remains unconverted and some is completely oxidized to form carbon dioxide and water. Formation of carbon monoxide is negligible. After the gases leaving the absorber is as follows: 9.6%CO2, 3.0%O2 and 6.4% ethylene. Of the ethylene entering the reactor, what percentage is converted to ethylene oxide?In biological systems, enzymes are used to accelerate the rates of certain biological reactions. Glucoamylase is an enzyme that aids in the conversion of starch to glucose (a sugar that cells use for energy). Experiments show that 1 μg mol of glucoamylase in a 4% starch solution results in a production rate of glucose of 0.6 μg mol/(mL)(min). Determine the production rate of glucose for this system in units of lb mol/(ft3)(day). A. 0.0015 lb mol/(ft3)(day) B. 0.0315 lb mol/(ft3)(day) C. 0.0539 lb mol/(ft3)(day) D. 0.3569 lb mol/(ft3)(day)

In this problem we consider a heat engine functioning via a four-step thermody cycle known as the Otto cycle. This cycle is an idealization of the operation of a gasoline engine or any other engine with spark plugs (note that the steps of the four-step cycle here should not be confused with the strokes of a four-stroke engine). = 0.500 L, PA = - - In Step 1 the gas in a cylinder undergoes a feversible adiabatic compression from an initial state with VA 1 bar, TA 300 K to volume VB (compression ratio = VA/VB = 10.8). In Step 2, the gas is reversibly heated at constant volume Vc = VB to To = 3000 K (this step approximates the heating of the gas due to the spark-initiated combustion of fuel injected prior to Step 1, with To being a reasonable guess at the temperature of the flame). In Step 3 the gas performs work by reversible adiabatic ex- pansion back to the original volume V₁. In the final step, the gas returns to the original pressure and temperature at constant volume (this step…
