5.88 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 sep arating it from impurities. The decomposition reaction is (b) How does the PV / R * T value of C*H_{4} compare to that in Figure 5.18? Explain.

(a) What is the final pressure of the confined gas (ignore the vol ume of graphite and use the van der Waals equation)?

Assume that decomposition begins at 10 degrees * C and 50.0 atm with a gas density of 0.215g / m * L and the temperature increases by 950 K.

CH 2 =CH 2 (g) longrightarrow CH 4 (g)+C(gr epsilon )
