Explain Heat of Combustion ;
The heat of combustion of a fuel is the heat released during combustion. Heat of combustion is used to measure the amount of heat released from a fuel. The heat of combustion is measured in kilojoules per mole. Heat of Combustion – Explanation Units .

There are two kinds of enthalpy of combustion, called high(er) and low(er) heat(ing) value, depending on how much the products are allowed to cool and whether compounds like H2O are allowed to condense.
That is, the heat of combustion, ΔH°comb, is the heat of reaction of the following process:
- C
cH
hN
nO
o (std.) + (c + h⁄4 – o⁄2) O
2 (g) → cCO
2 (g) + h⁄2H
2O (l) + n⁄2N
2 (g)
Chlorine and sulfur are not quite standardized; they are usually assumed to convert to hydrogen chloride gas and SO
2 or SO
3 gas, respectively, or to dilute aqueous hydrochloric and sulfuric acids, respectively, when the combustion is conducted in a bomb containing some quantity of water.
Units of Heat of Combustion of a Substance
A unit of heat of combustion is the amount of heat released when a unit of a substance is combusted. The amount of heat released can vary depending on the substance and the conditions of the combustion reaction.
Determination of Heat of Combustion
The heat of combustion of a fuel is the amount of heat released when the fuel is burned completely in oxygen.
Let Us Discuss Determining Each Type of Heat of Combustion
The heat of combustion of a fuel is the heat released when the fuel is completely oxidized. There are three types of heat of combustion: standard heat of combustion, net heat of combustion, and gross heat of combustion.
