Answer 1

a, \(\left(C_6H_{10}O_5\right)_n+nH_2O\underrightarrow{^{t^o,H^+}}nC_6H_{12}O_6\)

\(C_6H_{12}O_6\underrightarrow{^{t^o,xt}}2C_2H_5OH+2CO_2\)

\(C_2H_5OH+O_2\underrightarrow{^{t^o,mengiam}}CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH⇌CH_3COOC_2H_5+H_2O\) (đk: t^o, H₂SO₄ đặc)

b, \(C_{12}H_{22}O_{11}+H_2O\underrightarrow{^{t^o,xt}}C_6H_{12}O_6+C_6H_{12}O_6\)

\(C_6H_{12}O_6\underrightarrow{^{t^o,xt}}2C_2H_5OH+2CO_2\)

c, \(C_2H_4+H_2O\underrightarrow{^{t^o,xt}}C_2H_5OH\)

\(C_2H_5OH+O_2\underrightarrow{^{t^o,xt}}CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH⇌CH_3COOC_2H_5+H_2O\) (đk: t^o, H₂SO₄ đặc)
