The most unsuitable reactor for carrying out reactions in which high reactant concentration favours high yields is
Use tabulated thermodynamic data to find ΔG° for this reaction at the standard temperature of 25°C. Then calculate the calculate ΔG°1000 for this process when it occurs at 1000 K.
Assuming that sucrose is produced by the reaction: 12CO2(g)+11H2O(l) yields C12H22O11(s) 12O2(g); delta H=5640kj calculate the percentage of sunlight used to produce the sucrose- that is, determine the efficiency of photosynthesis.
An elementary second order adiabatic reaction A+ B CD ? + is taking place in a CSTR. The feed to the reactor is equimolar A and B at concentrations of 2.4 mol/liter. The entering temperature is 300 K.
Acetone is to be extracted from a solution in water, using 1,1,2-trichloroethane. The feed concentration is 45.0% w/w acetone. Determine the number of stages required to reduce the concentration of acetone to below 10%, using 32 kg of extraction-s..
Estimate the molar ratio of hydrogen to carbon monoxide in the synthesis gas if the feed consists of an equimolar mixture of steam and methane.
Please answer these simple five questions on fabrication engineering at the micro and nanoscale.
a. What is the melting point at standard conditions for ammonia? Boling point is given -33.4C. b. What is the enthalpy change for boiling ammonia at 0C?
Plot the system curve on the pump characteristic given in Figure and determine the operating point and pump efficiency. Properties of the fluid: density 900 kg/m3, viscosity 1.36 mN m-2 s.
Determine the values of the constants a and c and state the units and draw the path on a PV diagram also draw Path on the diagram and calculate the heat and work interchanges between the system and surroundings.
If 199 atoms of bohrium-267 could be synthesized, how much time would elapse before only 11 atoms of bohrium-267 remain? What is the expected electron configuration of elemental bohrium?
Which do you think would be the greater health hazard: the release of a radioactive nuclide of Sr or a radioactive nuclide of Xe into the environment? Assume the amount of radioactivity is the same in each case.
the dot regulation at 49 cfr 174.450 previously stipulated that when fire occurs in a domestic rail shipment of
