A Small reaction bomb fitted with a sensitive pressure-measuring device is flushed out andfilled with pure reactant A at 1atm. Pressure. The operation is carried out at 25oC,atemperature low enough that the reaction does not proceed to any appreciable extent. Thetemperature is then raised as rapidly as possible to 1000C and the following readings arerecorded. The stoichiometry of the reaction is 2A?B and after leaving the bomb in the bathover the weekend the contents are analyzed for A, none can be found. Find a rate equationwhich will satisfactorily fit the data;
The overall reaction in a commercial heat pack can be represented as: 4Fe(s)+ 3O2(g) yields 2Fe2O3(s); delta H=1652 kJ a. How much heat is released when 4.00 mol iron is reacted with excess O2?
One type of commercial smoke detector contains a minute amount of radioactive americium-241 (241Am), which decays by -particle production.
A continuous distillation unit, consisting of a perforated-tray column together with a partial reboiler and a total condenser, is to be designed to operate at atmospheric pressure to separate ethanol and water. The feed, which is introduced into t..
A continuous filter is used to separate a clear filtrate from alumina particles in a slurry. The slurry has 30% by weight of alumina (specific gravity of alumina = 4.5). The cake retains 5% by weight of water. For a feed stream of 1000 kg/hr, determi..
1) Give a common everyday example of fluid dynamics.
Hydrogen chloride gas, produced by burning chlorine with hydrogen, is required at a supply pressure of 600 kN/m2, gauge. The pressure can be achieved by either operating the burner under pressure or by compressing the hydrogen chloride gas.
Carry out a sensitivity analysis on the adipic acid project described in Example 9.5. Investigate the sensitivity of the 10-year NPV to variation in total fixed capital (-20% to +50%), annual gross profit (-20% to +30%), and project construction s..
The effect of a hazardous substance depends on the concentration of the substance that is present in the body's systems. The concentration depends on the stages of toxicokinetics What are the four main stages of toxicokinetics
Using the data given in Appendix C (available online at booksite .Elsevier.com/Towler), calculate the gross and net calorific values of the gas. Give your answer in MJ/m3, at standard temperature and pressure.
Express the maximum radius (Rmax) and maximum thickness (Tmax) in terms of bulk oxygen concentration, Cb (mol/mL), diffusivity of oxygen through the device D (cm2/s) and maximum oxygen consumption rate, Vmax (mol/mL/s).
Two equilibrium stages at 25C are used as shown in the following diagram. If 300 kg H2O/h is fed to each extraction unit, what fraction of the acetone in the feed solution would be removed and what would be the composition of the combined extract?
