Low density polyethylene (LDPE) is produced in a long tubular reactor under harsh conditions (T = 200 �C and 1800 bar). Ethylene is pressurized, mixed with catalyst, and pumped into the reactor where (LDPE) is produced. The reactor itself is 0.5 m in diameter and 1800 m in length. a)What phase is the ethylene? How can you tell?
