How is hess's law applied in calculating enthalpy

Hess's law states that the change of enthalpy in a chemical reaction (i.e. the heat of reaction at constant pressure) is independent of the pathway between the initial and final states. ... Hess's law allows the enthalpy change (ΔH) for a reaction to be calculated even when it cannot be measured directly.

Explanation:

To develop a strategy for the order in which you add the various equations.

In a Hess’s Law problem, you have to develop a strategy for the order in which you add the various equations. hope this helps <3

thats a little if u want the answer just look it up on google thats what i do haha : )

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa
