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 75%. [Hint: conversion = amount reacted / amount feed.
