The enthalpy value of an intermediate reaction refers to the change in enthalpy during the formation or transformation of an intermediate species in a reaction pathway. It is not typically a standalone value but is part of the overall enthalpy change of the entire reaction. The enthalpy of intermediates can be influenced by the stability of the intermediate and the surrounding reaction conditions. Generally, intermediates have higher enthalpy values compared to the reactants and products due to being less stable.
To reverse a reaction in a Hess's Law problem, you must change the sign of the enthalpy change associated with that reaction. For example, if the original reaction has an enthalpy change of ΔH, the enthalpy change for the reversed reaction would be -ΔH. This means you would use the negative value of the original enthalpy change as the final value for the enthalpy of reaction for the intermediate.
If you multiply a reaction by 2 in a Hess's law problem, you also need to multiply the enthalpy change (( \Delta H )) of that reaction by 2. For example, if the original enthalpy of reaction is ( \Delta H ), the enthalpy for the intermediate reaction will be ( 2 \Delta H ). This ensures that the thermodynamic properties remain consistent with the stoichiometry of the modified reaction.
To reverse a reaction in a Hess's Law problem, you must take the negative of the enthalpy change (( \Delta H )) for that reaction. If the original reaction has an enthalpy of ( \Delta H ), then the enthalpy value you would use for the reversed reaction as an intermediate would be (-\Delta H). This ensures that the direction of the reaction is correctly accounted for in the overall calculation.
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.
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.

The enthalpy value of an intermediate reaction refers to the change in enthalpy during the formation or transformation of an intermediate species in a reaction pathway. It is not typically a standalone value but is part of the overall enthalpy change of the entire reaction. The enthalpy of intermediates can be influenced by the stability of the intermediate and the surrounding reaction conditions. Generally, intermediates have higher enthalpy values compared to the reactants and products due to being less stable.
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?
It is multiplied by 2 if the intermediate reaction is multiplied by 2

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.
