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.

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.

The correct answer is option 1) Hess' law states that the standard reaction enthalpy is dependent on the route taken.

What is Hess law explain it?

Hess's Constant Heat Summation Law (or only Hess's Law) states that the overall change in enthalpy for the solution is the sum of all changes independent of the different phases or steps of a reaction. This rule is a discovery that enthalpy is a part of the state.

What is an example of Hess law?

For example, carbon reacts with oxygen to form carbon dioxide in excess oxygen. Carbon and oxygen combine to form carbon dioxide directly or in two steps -initially form carbon monoxide and then go to carbon dioxide.
