The enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a chemical reaction is the change of heat during this 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.
-572 k

572 kJ (just multiply like you would in algebra)
The enthalpy of a reaction does not depend on the intermediate reactions.
It is multiplied by 2 if the intermediate reaction is multiplied by 2
1410 kJ
The enthalpy of a reaction does not depend on the reactant path taken.
The enthalpy of a reaction is the sum of the enthalpies of intermediate reaction.
