  • Câu hỏi:

    Crăking C4H10 được hỗn hợp Y gồm H2, CH4, C2H4, C2H6, C3H6, C4H8 và C4H10 dư. Biết \(\overline{M}_{Y}=32,22\) gam/mol. Hiệu suất phản ứng cracking là:

    Sản phẩm không có C4H6
    C4H10 → Ankan(H2) + Anken
       a     →      a                a
    dư: b
    \(\overline{M}_{Y}=32,22\)
    Lấy (C4H10) ⇒ \(m_{C_{4}H_{10}}\) = mY = 58 g
    \(\Rightarrow n_{Y}=\frac{m_{Y}}{\overline{M}_{Y}}=\frac{58}{32,22}=1,8 \ mol\)
    \(\Rightarrow n_{C_{4}H_{10}}=1=a+b\)
    \(\\ n_{Y}=1,8=2a+b \\ \Rightarrow a=0,8, \ b=0,2 \\ H\% = \frac{a}{1}=\frac{0,8}{1}=\frac{80}{100}\)
