What are the empirical formulas for calculating enthalpy?
Thread Content
When working on my course project, I encountered some enthalpies that I couldn’t find. I would like to ask everyone what empirical formulas are available for calculating enthalpy.
There are many in physical chemistry; you’ll have to look for them on your own.
Reply to 2# kzb7054: But some of the calculations are incorrect. Everyone is using those same values, right?
This question is too general; different formulas are applicable under different conditions. Check whether the assumptions behind the formula you’re using match the conditions given in the problem.
Enthalpy H = U + PV. Enthalpy does not have an absolute value; only the change in enthalpy can be calculated. Enthalpy is a function of temperature!
Generally, no estimation is needed. I specialize in calculations related to chemical reaction equilibrium (Kp, Cp, H, S, G). If you need such services, feel free to contact me (sorry, there will be a fee required): zyaqsm@163.com
