If you need to multiply the reaction by 2, you must also multiply the enthalpy change by 2. The final value for the enthalpy of the reaction used for the intermediate reaction would be 2 times the original enthalpy value.
When you multiply a reaction by a factor, you also multiply the enthalpy change by the same factor. Therefore, if you multiply the reaction by 2, the final value for the enthalpy of reaction for the intermediate reaction will also be multiplied by 2.
Can you please provide me with the specific reaction or context for which you need the enthalpy value?
The final value for the enthalpy of the reverse reaction used in a Hess's law problem would simply be the negative of the original value of the enthalpy of the forward reaction. This is because reversing a reaction changes the sign of the enthalpy change.

By the intermediate of a chemical reaction a compound is transformed in another compound.
The enthalpy of a reaction is the sum of the enthalpies of intermediate reaction.

To reverse a reaction in a Hess's law problem, you need to change the sign of the enthalpy change associated with that reaction. If the original reaction has an enthalpy of reaction ( \Delta H ), the final value for the enthalpy of the reversed reaction would be ( -\Delta H ). This allows you to correctly account for the energy change in the overall pathway when combining reactions.
An intermediate state is a stable molecule formed during a chemical reaction, while a transition state is a high-energy, unstable state that exists briefly during the reaction. The intermediate state is a product of the reaction, while the transition state is a point where the reactants are in the process of forming products.
