Ethanol was oxidised to acetic acid in a...

Ethanol was oxidised to acetic acid in a catalyst chamber at `18^(@)C`. Calculate the rate of removel of heat to maintain the reaction chamber at `18^(@)C` with the feed rate of `30 kg h^(-1)` ethanol along with excess oxygen to the system at `18^(@)C`, given that a `42 mol%` yield based on ethanol is obtained. Given that
`Delta_(f)H^(Theta)underset(H_(2)O)'(l) =- 68.0 kcal mol^(-1)`
`Delta_(f)H^(Theta)underset(C_(2)H_(5)OH)'(l) =- 66 kcal mol^(-1)`
`Delta_(f)H^(Theta)underset(CH_(3)COOH)'(l) =- 118 kcal mol^(-1)`

Text Solution

Verified by Experts

`C_(2)H_(5)OH+O_(2)toCH_(3)COOH+H_(2)O`
`DeltaH=sum(H_(f))_(P)-sum(H_(f))_(R)=(-118-68.4)-(-66)=-120.4` kcal
Yield is 42% Thus, energy produced per hour will be
`=(120.4xx42xx30000)/(100xx46)=32979.13" kcal hour"^(-1)`
