The gas that comes out of a gasoline stabilizer has the following composition by volume: C₃H₈ 8%, CH₄ 78%, C₂H₆ 10%, and C₄H₁₀ 4%. This gas that comes out at 90 ° F and 16 psi of absolute pressure is supplied at the rate of 70,000 ft³ / h to a gas conversion plant, where the following reactions take place:

CnH2n + 2 + n H2O n CO + (2n + 1) H2

CO + H2O CO2 + H2.

CnH2n + 2 gases are converted to 95% and 90% of CO that also reacts, depending on the reactions. Make a process diagram and calculate:

a) Average molecular weight of the gas coming out of stabilizer.

b) Weight of the gas supplied to the conversion plant in lb / h.

c) Weight of the H2 that leaves the converter plate in lb / h.

d) Composition in volume of the gases that leave the converter plant.

Thank you!

41.At 1024°C, the pressure of oxygen gas from the decomposition of copper(II) oxide (CuO) is 0.490 atm: 4CuO(s) ⇆ 2Cu2O(s) + O2(g) (a) What is KP for reaction? (b) Calculate the fraction of CuO decomposed if 0.560 mole of it is placed in a 2.00 L flask at 1024°C. (c) What would be the fraction if a 1.00 mole sample of CuO were used?

40.A quantity of 0.29 mole of carbon dioxide was heated to a certain temperature with an excess of graphite in a closed container until the following equilibrium was reached: C(s) + CO2(g) ⇌ 2 CO(g) Under these conditions, the average molar mass of the gases was 35.9 g/mol. (a) Calculate the mole fractions of CO and CO2. The mole fraction of CO is The mole fraction of CO2 is (b)What is KP if the total pressure is 11.1 atm?

The relationship between the amount of remaining carbon monoxide (CO) in an individual’s lungs and the time since that person last smoked a cigarette can be summarized using a linear regression approach.

(a) Write down a simple linear regression model and the underlying assumptions. The following summary data was collected from 12 different smokers. x = time since last smoked a cigarette (hours) y = amount of CO in ppm n=12, x=1.88 sxx =25.8, syy =1805 SSE=877.4 Fitted regression line: ?̂ = ??. ?? − ?. ??? ?

(b) State the values of ? and ? from the fitted regression equation. Not that ? and ? are the estimates of intercept parameter ? and slope parameter ? respectively.

(c) What is the estimated change in the remaining CO in the lungs if the time since last smoked is increased by 1 hour?

(d) State the hypotheses to test the significance of the linear regression.

(e) Compute MSE.
