Which is true of the enthalpy of a reaction?
Its value does not depend on which reactions are added.
How do you calculate the enthalpy change of a reaction?
To calculate the enthalpy change of a reaction, subtract the total enthalpy of the reactants from the total enthalpy of the products. This difference represents the enthalpy change of the reaction.
What is the enthalpy change for the reverse reaction?
The enthalpy change for the reverse reaction is equal in magnitude but opposite in sign to the enthalpy change for the forward reaction.
What is true of the enthalpy value of an intermediate reaction?
It is multiplied by 2 if the intermediate reaction is multiplied by 2
Is the reaction endothermic or exothermic, and what is the enthalpy of the reaction?
The reaction is exothermic, meaning it releases heat. The enthalpy of the reaction is negative, indicating that it is exothermic.

What is true of the enthalpy value of an intemediate reaction?
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.

What is the description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.

What does Hess's law say about the enthalpy of a reaction?
The enthalpy of a reaction does not depend on the reactant path taken.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
