Which of the following is incorrect about Hess Law?

1. Hess' law states that the standard reaction enthalpy is the dependent on the route taken

2. The enthaphy change of a reaction is independent of the route taken

3. Hess' law states that when chemical equations are combined algebraically, their enthalpies can be combined in exactly the same way ... If a chemical reaction is reversed, the sign on ΔH is changed. If a multiple of a chemical reaction is taken, the same multiple of the ΔH is taken as well.

4. Enthalpy change for a reaction is independent of the number of ways a product can be obtained, if the initial and final conditions are the same.

Explanation:

Hess's law states that that the total enthalpy change during the complete course of a chemical reaction is the same whether the reaction is made in one step or in several steps.
