Hess’s law is based upon the fact that enthalpy is a state function, or in other words, the enthalpy change of a reaction depends only on the enthalpy of the initial reactants and the enthalpy of the final products formed in the reaction. The path of the reaction does not have any i...
Hess Law: Hess Law shows that the change in enthalpy remains the same (a state function). The enthalpy change is independent upon the path. There are also many other terms that are state function, such as internal energy, entropy etc. ...
What is the major premise of Hess's Law?Enthalpy Change:Enthalpy change refers to the amount of heat released or absorbed in the course of a reaction. Enthalpy change is one of the factors that can be used to determine whether a reaction will occur....
