What is true of the enthalpy reaction?
Its value does not depend on which reaction are added
What is true of the enthalpy value of an intermediate reaction?
It is multiplied by 2 if the intermediate reaction is multiplied by 2
What does the enthaply of reaction measure?
The enthalpy of reaction is the change of the system enthalpy after a chemical reaction.
What is a correct description of the enthalpy of a reaction?
The enthalpy of a reaction does not depend on the intermediate reactions.
What is the Hess's law?
C - The enthalpy of reaction does not depend on the steps taken in the reaction. APEX --WXM--

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.
What is a correct description of the enthalpy of a reaction?
The enthalpy of a reaction does not depend on the intermediate reactions.
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.
True or False A large positive value of entropy tends to favor products of a chemical reaction?
True, a large positive value of entropy tends to favor products of a chemical reaction. However, entropy can be offset by enthalpy; a large positive value of enthalpy tends to favor the reactants of a chemical reaction. The true measure to determine which side of a chemical reaction is favored is the change in Gibbs' free energy, which accounts for both entropy and enthalpy, as calculated by: Change in Gibbs = Change in Enthalpy - Temp in Kelvin * Change in Entropy A negative value of Gibbs free energy will always favour the products of a chemical reaction.
