Question

Does anyone know how to calculate enthalpy? Thank you! ^^

Answer 1

the most direct way is to look up enthalpy values from a table in a text, then subtract the enthalpies of all the reactants from the enthalpies of all the products

Answer 2

You have three methods in order to calculate enthalpy
1-Hess Law
2-Using Bond energy values from the data booklet
3-Using the equation ( Enthalpy of products-Enthalpy of reactants)
That is all I remember for now :)
Good luck!
