I've google and read, but could anyone tell me how to find out the standard enthalpy of formation for any compound?
thnx
thnx
For any compound you say? That might be difficult.Juwad said:for any compound?

Sankalp Goyal said:I want to know the standard enthalpy and entropy values for the following:
TiN (Titanium Nitride)
TiC (Titanium Carbide)
VC (Vanadium Carbide)
VN (Vanadium Nitride)
The Standard Enthalpy of Formation, also known as the Standard Heat of Formation, is the amount of heat released or absorbed when one mole of a compound is formed from its constituent elements in their standard states at a given temperature and pressure.
The Standard Enthalpy of Formation is measured using a calorimeter, which is a device that measures the heat of a reaction. The reactants and products are placed in the calorimeter and the change in temperature is recorded, which can then be used to calculate the enthalpy change.
The Standard Enthalpy of Formation is important for determining the stability and energy content of a compound. It is also used to calculate the enthalpy change of a chemical reaction, which is essential for studying and predicting the behavior of chemical reactions.
The Standard Enthalpy of Formation is related to other thermodynamic properties, such as the Standard Enthalpy of Reaction and the Standard Enthalpy of Combustion, through Hess's Law. This law states that the overall enthalpy change of a reaction is independent of the pathway taken to reach the final products.
The Standard Enthalpy of Formation can be affected by temperature, pressure, and the physical state of the reactants and products. It can also be influenced by the presence of impurities or other reactants that may participate in side reactions.
