Safety considerations dictate that at a temperature of 320 K the liquid must occupy no more that 75 percent of the total volume of the vessel. For these conditions, determine the mass of the vapour in the vessel using the Redlich-Kwong equation of state. At 320 K the vapour pressure of propane is 16.0 bar.

Times New ... A Questions 1. What causes the liquid to move one direction or the other in the U-shaped part of the apparatus? You may wish to read the explanation found on the experiment webpage by clicking on "Isoteniscope Method" inside the red box (the explanation will appear in a pop-up window). 2. Does it matter in this experiment how much of the liquid phase was present? Explain your answer. 3. a. Look at the value of the vapor pressure at approximately 35°C for both ethanol and cyclohexane in your data Record these values here.

Use theMcCabe–Thiele method to compute, at 1 atmnumber of equilibrium stages N, for R/Rmin = 1:3,and the optimal feed-stage location for benzene distillate and bottoms purities of 99.9 and 0.1 mol%, respectively, using a reflux ratio of 1.88, which is about 30% higher than the minimum reflux of 1.44.At the top of the column, α = 2.52; at the bottom, α = 2.26.

5. The following are short answer questions concerning chromatography. a. b. C. In GC, you learned that H, gas has some advantages over using He gas. What are two advantages? If you are using uv/vis absorption to detect analytes coming off a chromatography column, why are you more likely to measure peak area that peak height when making a graph of signal versus concentrations for the standards? The van Deemter equation can be written as: H = A + B/u + Cu Give brief explanations for the A, B, and C terms. Be sure to explain how each term is affected by the flow rate of the mobile phase.

Each of the intermediate distillate products appears to be shown as a side stream removed from the column as a vapor stream from a stage. What (if any) benefit would you suggest there might be for pulling a side stream as a vapor (instead of drawing off the liquid from the stage)?

When 11.5g of Carbon reacts with 114.5 g of Copper(1) oxide, 87.4 g of Copper are obtained. Determine the limiting reactant, theoretical yield, and percent yield. 144

7 A flammable liquid is being transferred from a road tanker to a bulk storage tank in the tank farm. What control measures would help reduce the risk of vapour ignition due to static electricity.?

Explosions occur when the rate of reaction increases dramatically over a short period of time. There are several types of explosions such as autocatalytic explosions, thermal explosions and branched chain explosions. The mole balance of radical species in branched chain reaction can be expressed as: (Refer attachment) With appropriate assumption, prove that the branched chain explosion can occur exponentially and provide two (2) ways to prevent the occurrence of radical chain explosion in chemical laboratory.
