The Gibbs Helmholtz equation predicts that the equilibrium constant for calcium carbonate decomposition does not exceed 1.0 at 1000 K

1.Heavy multicore processors

2.Lightweight cores with SoC characteristics: memory controllers and I/O on die

3.GPUs.

Discuss these three classes processor architectures briefly and describe their basic properties such as memory organization, communication interconnection, and number and complexity of their processing units comparatively. Exemplify their application domains with about three applications for each class, justifying your answer. Which of these processors would be suitable for smartphones, laptops, and even high-performance clusters, if any? Justify your answer.

Define polycrystalline. Are most materials polycrystalline or single crystals? What, if any, considerations should be taken when conducting XRD on single crystals?

What practical application arises from the wave-particle duality of electrons? Explain

Coke can be converted into CO in following reaction CO₂(g) + C(s) -> 2CO(g). A coke that contains 84% carbon by mass and the balance noncombustible ash is fed to a reactor with a stoichiometric amount of CO₂. The coke is fed at 77 oF, and the CO₂ enters at 400 oF. Heat is transferred to the reactor in the amount of 5800 btu/lbm coke fed. The gaseous products and the solid reactor effluent (the ash and unburned carbon) leave the reactor at 1830 oF. The heat capacity of the solid is 0.24 btu/(lbm.oF)   

Calculate the percentage conversion of the carbon in the coke. (Provide your answer in decimal format, NOT percentage format!)

How much coal must be burned each day to produce enough energy to generate the steam to run the turbines to produce enough electricity to meet the daily power requirements of a city of 500,000 people? Note: If the average house hold has 4 people and the average annual electricity consumption for a residential utility customer is 10,932 kilowatthours (kWh), an average of 911 kWh per month. Write a full lab report with objective, theory of coal burning to produce steam to generate electricity, flow chart of the complete process, all calculations, discussion and conclusion.

This is set of homogeneous and gas phase reactions: A-->B-->C . The reaction scheme is carried out in a constant volume, ideal batch reactor at constant temperature. The first reaction is first order with respect to A with a rate constant k1 while the second reaction is zero order with a rate constant k2. Initially, the reactor contains only A at a concentration CA0. a) Derive expressions for the concentration of A, B, and C as a function of reaction time t

b) If k1 = 0.5 h−1, k2 = 3 mol/m3·h, and CA0 = 30 mol/m3, find the optimal time to reach a maximum yield of the desired product B, where yield is defined as YB/A = CB/CA0. What is the corresponding value of the maximum yield at this point in time? What constraints (if any) need to be placed on k1, k2, and/or CA0 in order to observe a maximum in the yield?

1) Why is the resistivity of the filter cake (the solid) higher than resistivity of filtrate, for after doing the filtration drilling fluids?

2) Should drilling fluids be high in resistivity or low? and why?

An adult inhales approximately 12 times per minute, taking in about 500 mL of air with each inhalation. Oxygen and carbon dioxide are exchanged in the lungs, but there is essentially no exchange of nitrogen. The exhaled air has a mole fraction of nitrogen of 0.75 and is saturated with water vapor at body temperature, 37°C. If ambient conditions Professor Christina Tang, [email protected] 2 are 25°C, 1 atm and 50% relative humidity, determine what volume of liquid water (mL) would have to be consumed over a two hour period to replace the water loss from breathing.

(a) How much water would have to be consumed on an airplane where the temperature, pressure and relative humidity are 25°C, 1atm and 10%, respectively.
