Question

3. Ethylene can be formed by catalytic cracking of propane:

C3H8 ? C2H4 ?CH4

This reaction is carried out in the gas phase.

a) Calculate the standard Gibbs Energy of the reaction (????? 0 ) and equilibrium constant of this reaction at K298.15 . Use Appendix C to retrieve the molar Gibbs Energy of formation of the individual compounds.

b) 1000 lb-mol/hr of n – propane enter a steady – state reactor, which is maintained at T = 298.15 K and P = 1 bar. Determine the composition of the exiting stream, assuming it is at equilibrium. Assume ideal gas behavior.
