The oxidation of nitric oxide takes place in an isothermal batch reactor. The reactor is charged with a mixture containing 20.0 volume percent NO and the balance air at an initial pressure of 380 kPa (absolute).
(a) Assuming ideal gas behavior, determine the composition of the mixture (component mole fractions) and the final pressure (kPa) if the conversion of NO is 90%.
(b) Suppose the pressure in the reactor eventually equilibrates (levels out) at 360 kPa. What is the equilibrium percent conversion of NO? Calculate the reaction equilibrium constant at the prevailing temperature, Kp [(atm)-0.5]
Determine the highest possible temperature that can be obtained when liquid octane (C8H18) at 25 degrees C is burned steadily with air at 25 degrees C.
Let the property P;.. in Eq 5.2-1 be the scalar 1 so that the integral in that equation represents the instantaneous volume V. Show that in this case
The mass transfer coefficients are HL=0.436 m and kGa=6.06x10-7kg mol/s m3Pa and are to be assumed constant in thetower for the given concentration range. Use equilibrium data from Appendix A.3. Bynumerical or graphical integration, determine NG. ..
At a flea market, you've found a very interesting painting done in the style of Rembrandt's "dark period" (1642-1672). You suspect that you really do not have a genuine Rembrandt, but you take it to the local university for testing. Living wood sh..
Choose an initial guess for reactor temperature and pressure within the range provided and simulate the process described - Determine a metric to quantify the reactor performance then use this parameter to optimize the reactor temperature and pressu..
oleum or fuming sulfuric acid available commercially in concentrations ranging from 20 to 99.9 sulfur trioxide. a.
Acetylene is formed as a by-product in the manufacture of ethylene. It is removed by selective hydrogenation using noble metal catalysts (see, for example, US 7,453,017). A particular catalyst achieves 90% acetylene saturation with 50% hydrogen se..
A 100-liter fed-batch fermenter was successfully operated for 200 h using an aeration rate of 14 l/s and a 5 W agitator. It is proposed to scale the fermentation up to 10,000 liters. What agitator power consumption is required?
In Bertrand competition firms decide independently what prices to set to maximizetheir individual profits. Suppose that there are two firms in a market sellingthe same product. Let D(p) = 9 - p be the market demand and let c1 = 1 andc2 = 7 be firm 1 ..
