Question 19 of 30
Why does Hess's law allow you to determine the enthalpy change of a
reaction?
A. It states that the enthalpy of any reaction can be determined using
a bomb calorimeter.
B. It states that the change in enthalpy is independent of the pathway
the reaction takes to get to the products.
C. It states how the equilibrium constant is related to the enthalpy
change.
D. It states that the change in enthalpy depends on the reaction
pathway between the products and the reactants.

Answer:

B.) It states that the change in enthalpy is independent of the pathway
the reaction takes to get to the products.

Explanation:

Hess's Law states that the overall enthalpy change is the sum of the enthalpy changes of all preceding steps. It does not matter how many steps there are or the type, so long as the enthalpy change of each is combined at the end, the overall change can be determined. The sequence (aka pathway) is not important.
