Question: Hess law of constant heat summation?
Hess's law of constant heat summation states that the enthalpy change of a chemical reaction is independent of the pathway between the initial and final states, as long as the initial and final conditions are the same. In other words, the total enthalpy change of a reaction can be calculated as the sum of the enthalpy changes of a series of intermediate reactions that lead from the initial state to the final state. This principle is based on the fact that enthalpy is a state function, which means it only depends on the initial and final states of a system, not on how the system got there.
