Redo Problem 13.37 using Aspen Plus.

Problem 13.37

At an appropriate temperature, a larger alkane will “crack” to form a smaller alkane and an olefin. One example is the cracking of propane to form methane and ethylene: 

a. Calculate the equilibrium compositions that would result at 298.15 K and a total pressure of 1 bar by starting with pure propane. 

b. Assuming that the standard-state heat of reaction for this reaction is independent of temperature, repeat the calculation above at 650 K. 

c. Repeat the calculation of part (b) for a total pressure of 10 bar, assuming that an ideal gas mixture is formed at this high temperature.
