a, PT: \(CH_3COOH+C_2H_5OH\underrightarrow{_{H_2SO_{4\left(đ\right)}}}CH_3COOC_2H_5+H_2O\)
b, Ta có: \(n_{CH_3COOH}=\dfrac{30}{60}=0,5\left(mol\right)\)
\(n_{C_2H_5OH}=\dfrac{27,6}{46}=0,6\left(mol\right)\)
Xét tỉ lệ: \(\dfrac{0,5}{1}< \dfrac{0,6}{1}\), ta được C2H5OH.
Theo PT: \(n_{CH_3COOC_2H_5\left(LT\right)}=n_{CH_3COOH}=0,5\left(mol\right)\)
\(\Rightarrow m_{CH_3COOC_2H_5\left(LT\right)}=0,5.88=44\left(g\right)\)
Mà: m CH3COOC2H5 (TT) = 35,2 (g)
\(\Rightarrow H\%=\dfrac{35,2}{44}.100\%=80\%\)
