1. You are asked to carry out the gas-phase hydrogenation of benzene to cyclohexane. a) What conditions of pressure and temperature (high/low) would result in maximum conversion? b) Determine the equilibrium composition of a mixture that contains 30% benzene (by mole) and 70% hydrogen at 200 °C, 5 bar. 2. Benzene is formed from the gas-phase dehydrogenation of cyclohexane according to the reaction: C6 H12 (g) = C6 H6 (g) + 3H2 (g). a) Calculate the standard heat of reaction and the equilibrium constant at 25 °C. b) A stream that contains 50% by mole cyclohexane in nitrogen is fed to a reactor that operates a constant pressure and temperature. The reactor pressure is 5 bar and the desired conversion of cyclohexane is 85%. Determine the amount of heat per mol in the feed that must be added or removed from the reactor in order to maintain the temperature constant. c) Determine the composition of all species at the exit of the reactor. d) Assuming the reaction reaches equilibrium, determine the reactor temperature. e) It has been suggested that conversion could be increased by operating at different pressure. You may vary the reactor pressure between 1 and 10 bar. If temperature and inlet conditions remain the same, at what pressure would you operate the reactor? Explain your answer. f) List all of your assumptions and explain where each assumption was used.

modify the Very Simple CPU to incorporate a new 8-bit register,R, and two new instructions. MVAC performs the transfer Râ†AC and has the instruction code 1110 XXXX; MOVR performs the operation ACâ†R and has the instruction code 1111 XXXX.
Can we build a bandpass filter using a low pass and a high pass filter combination. If your answer is yes, then how should the cut off frequencies be arranged. Illustrate your answer with a simple example.
What are two of the major considerations that factor in the design of a substation. Give a couple of examples of station layouts where these factors are clearly demonstrated. What typical grounding materials are used in substations.
Design a Moore machine that has one input X and one output Z. Provide a complete design using D Flip flops. In this design, the output should be 1 any time the sequence 01101 occurs. Overlapping sequences are allowed.
Assume that the I bit for external hardware interrupt IRQ is enabled and is low-level triggered. Explain how this interrupt works when it is activated. How can we make sure that a single interrupt is not interpreted as multiple interrupts

Consider a 4-PAM system with Gray mapping. Evaluate the exact bit error probability. Hint: Consider the bit error probability for the first and second bit separately, and then average over the two bit error probabilities. To find the error probab..
Your VHDL description should be structural and constructed from 3 behavioral VHDL 1-bit ALU blocks, a special behavioral VHDL 1-bit ALU block for the most significant bit and a behavioral VHDL block for the zero detect logic.
