Problem: Can you use an approach similar to Hess's law to calculate the change in internal energy, E, for an overall reaction by summing the E values of individual reactions that add up to give the desired overall reaction?

FREE Expert Solution

ΔH and ΔE are both state functions. A state function is a property whose value does not depend on the path taken to reach that specific value.
