Question

For the cracking reaction, C3H8(g) C2H4(g) + CH4(g) the equilibrium conversion is negligible at room temperature but becomes appreciable at temperatures above 500 K. For a pressure of 1 bar, neglecting any side reactions,

determine:

a. the temperature, where the conversion is 70%. [Hint: conversion = amount reacted/amount fed. Relate ζ to the conversion.]

b. the fractional conversion, which would be obtained at 550 K if the feed to a reactor is 50 mol% propane and 50 mol% nitrogen (inert). (Consider the reaction to proceed to equilibrium.)

For the cracking reaction,
C3H8(g) 2 C2H4(g) + CH4(g)
the equilibrium conversion is negligible at room temperature but becomes appreciable at
temperatures above 500 K. For a pressure of 1 bar, neglecting any side reactions,
determine:
a. the temperature, where the conversion is 70%. [Hint: conversion
reacted/amount fed. Relate 5 to the conversion.]
amount
b. the fractional conversion, which would be obtained at 550 K if the feed to a
reactor is 50 mol% propane and 50 mol% nitrogen (inert). (Consider the reaction
to proceed to equilibrium.)
