Differentiate elementary andnon-elementary reactions.?The reactions in which the rate equation corresponds to a stoichiometric equation arecalled elementary reaction.?The reactions in which there is no correspondence between stoichiometry and rateequation are known as Non-elementary reaction. and What are the various intermediates that can be formed in a non-elementary reaction?Free radicals, ions and polar substances, molecules, transition complexes are thevarious intermediates that can be formed ina non-elementary reaction
If the operating coil has 1800 turns carrying a current of 1 A, and the gaps are set at 0.125 cm each, find the pull that must be exerted by the spring. You may neglect leakage and fringing.
If EV, LE, are the distances between points (L, E) and (E, V) respectively (Fig. 2-3), show that the liquid and vapor fractions corresponding to point E satisfy the relationship
draw and label a flow chart the process. In addition to the process provided in the above flow sheet, Additional variables and relationships are defined. They are shown separately here for clarity
Piston arrangement: compressing air, A piston arrangement has been developed to compress air adiabatically from 360C
Discuss what is meant by critical mass, and explain why the ability to achieve a critical mass is essential to sustaining a nuclear reaction.
A certain gas has a molecular weight of 30.0 a critical temperature of 310K. and a critical pressure of 4.5MPa. Calculate the density in kg/m3 of this gas at 465 K and 9.0MPa
An alternative process for converting benzene to cyclohexane also uses a supported noble metal catalyst, but carries out the reaction in the liquid phase, at a temperature of 160 °C and pressure of 100 bare, in a slurry reactor.
Monczka-Trent has two options: (1) its standard 2-day shipment or (2) a subcontractor who will team drive overnight with an effective delivery of 1 day. The extra driver costs $175. Handfields's holding cost is 35% annually for this kind of inventory..
Monczka-Trent Shipping is the logistics vendor for Handfield Manufacturing Co, in Ohio. Handfield has daily shipments of a power-steering pump from its Ohio plant to an auto assembly line in Alabama.
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.
2.8 g of N2 gas at 300 k and 20 atm was allowed to expand isothermally against a constant external pressure of 1 atm. calculate del E ,q and W for the gas.
You are requested to flash the mixture so that the liquid stream is 85% of the inlet (by mol). If the pressure is 1.5 bar, what temperature should be used?
