Problem: The thermal decomposition of ethylene occurs during the compound’s transit in pipelines and during the formation of polyethylene. The decomposition reaction isCH2=CH2(g) ⟶ CH4(g) + C(graphite)If the decomposition begins at 10°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)?

Problem Details

The thermal decomposition of ethylene occurs during the compound’s transit in pipelines and during the formation of polyethylene. The decomposition reaction is

CH2=CH2(g) ⟶ CH4(g) + C(graphite)

If the decomposition begins at 10°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)?
