H chung = 80%.70%.62,5% = 35%
nC2H4 → -(CH2 – CHCl-)n
Phương trình: 28n → 62,5n (tấn)
Đề bài: x ← 1 (tấn)
x = 1.28n/62,5n = 0,448 tấn = 488kg
V C2H4 = 448 : 28 . 22,4 = 368,4 m3
H = 35% ⇒ V C2H4 cần dùng = 368,4 : 35% = 1024 m3
Đáp án B.
Đáp án C
Hướng dẫn
nPVC = 5000/62,5 = 80 kmol => mC2H4 = 80.100.28/80 = 2800kg
