Calculation of reaction enthalpy 7 (thermo-19)

Suppose you choose the unhealthy variant, that the total daily energy intake Drinking alcohol (40The following assumptions and specifications apply:

1. Drinking alcohol would be C₂H₅OH (Ethanol), density of pure alcohol 0.9 g/ml
2. Assumption: the alcohol is inhaled in the body, i.e. O₂ implemented.
3. Notes 1: First calculate the reaction enthalpy, including the aggregate state
4. Notes 2: Calculate from ΔHoR and the amount of ethanol per litre of alcohol the amount needed to realize the energy supply
5. Notes 3: Daily energy needs 9200 KJ
6. Notes 4For the professionals: the calculation basis is not complete, in fact the free-reaction enthalpy should be For details, see the following task: thermo-108But you can see that the result It 's just about . 10 % would change
