Question: Which law states that the total enthalpy change in a reaction is the same regardless of the number of steps in the reaction?

Options:

Correct Answer: Hess\'s Law

Solution:

Hess\'s Law states that the total enthalpy change for a reaction is the same, regardless of whether it occurs in one step or multiple steps.

Which law states that the total enthalpy change in a reaction is the same regardless of the number of steps in the reaction?

Which law states that the total enthalpy change in a reaction is the same regardless of the number of steps in the reaction?

Step 1: Understand what enthalpy change means. It is the heat content change during a chemical reaction.
Step 2: Learn about Hess's Law. It says that the total enthalpy change for a reaction is the same no matter how many steps the reaction takes.
Step 3: Realize that this means if a reaction can happen in one step or several steps, the total energy change will be the same.
Step 4: Remember that Hess's Law helps us calculate the enthalpy change for complex reactions by breaking them down into simpler steps.
