-1368 kJ mol-1
Combustion reactions
The reaction is :- C2H5OH + 3O2--- 2CO2 + 3H2O
When flame is applied to ethanol (C2H5OH), it undergoes combustion, a chemical reaction where it reacts with oxygen (O2) in the air to produce carbon dioxide (CO2), water (H2O), and heat. The balanced chemical equation for the combustion of ethanol is: C2H5OH + 3O2 → 2CO2 + 3H2O In this reaction, the ethanol molecule breaks apart, and its carbon and hydrogen atoms combine with oxygen atoms from the air to form carbon dioxide and water vapor, respectively. This reaction releases a significant amount of heat energy, which is why ethanol is used as a fuel in alcohol burners, stoves, and engines. When you observe a flame applied to ethanol, you will see a blue-colored flame, indicating complete combustion. The heat produced by the combustion of ethanol can be used for various purposes, such as heating, cooking, or powering engines.
Your question is not right.ethanol is also know as ethyl alcohol. When you take the preparations of ethanol,here it acts as product example ethane reacts with water to give ethanol C2H4+H2O gives C2H5OH in this example ethanol is a product. When we take chemical or physical properties of ethanol it act as reactent in the chemical equation. Example-combustion or burning of ethanol in air gives carbon dioxide and water. C2H5OH+3O2 gives 2CO2+3H20 in the above example ethanol is a reactent.
Combustion of ethanol with oxygen: C2H5OH + 3 O2 --> 2 CO2 + 3 H2O + 'Heat'
-1277.36kJ is the heat of combustion of ethanol. It is not the heat of fermentation for the production of ethanol.
There are two angles to this question: 1. If your ethanol is contaminated with water it will reduced the amount of useful heat generated since the water will boil off while the ethanol is burning. 2. The water generated as a result of combustion is included as a term in the calculation of heat of combustion.
All types of combustions are exothermic.
The complete combustion of ethanol in oxygen proceeds according to the balanced equation C2H6O + 3 O2 -> 2 CO2 + 3 H2O.
Combustion of Ethane: 2C2H6+7O2-->4CO2+6H2O Combustion of Ethanol: C2H5OH+3O2-->2CO2+3H2O
C2H5OH + 3O2 --> 2CO2 + 3H2O Ethanol + Oxygen --> Carbon Dioxide + Water
-1368 kJ mol-1
Water can be a product of combustion.
