\(n_{hh}=\dfrac{4,48}{22,4}=0,2mol\)
\(n_{Br_2}=\dfrac{48}{160}=0,3mol\)
Gọi \(\left\{{}\begin{matrix}n_{C_2H_2}=x\\n_{C_2H_4}=y\end{matrix}\right.\)
\(C_2H_2+2Br_2\rightarrow C_2H_2Br_4\)
x 2x ( mol )
\(C_2H_4+Br_2\rightarrow C_2H_4Br_2\)
y y ( mol )
Ta có:
\(\left\{{}\begin{matrix}x+y=0,2\\2x+y=0,3\end{matrix}\right.\) \(\Leftrightarrow\left\{{}\begin{matrix}x=0,1\\y=0,1\end{matrix}\right.\)
\(\rightarrow\left\{{}\begin{matrix}\%V_{C_2H_2}=\dfrac{0,1}{0,2}.100=50\%\\\%V_{C_2H_4}=100\%-50\%=50\%\end{matrix}\right.\)
