The thermal decomposition of ethylene occurs in many
Chapter 6, Problem 88P(choose chapter or problem)
The thermal decomposition of ethylene occurs in many industrial contexts, for example, during ethylene transit in pipelines, formation of polyethylene, drying of the gas, and separating it from impurities. The decomposition reaction is
\(\mathrm{CH}_{2}=\mathrm{CH}_{2}(g) \longrightarrow \mathrm{CH}_{4}(g)+\mathrm{C} \text { (graphite) }\)
Assume that decomposition begins at \(10^{\circ} \mathrm{C}\) and \(50.0 atm\) with a gas density of \(0.215 g/mL\) and the temperature increases by \(950 K\).
(a) What is the final pressure of the confined gas (ignore the volume of graphite and use the van der Waals equation)?
(b) How does the PV/RT value of \(\mathrm{CH}_{4}\) compare to that in Figure 5.18? Explain.
