Which is true of the enthalpy of a reaction?
Its value does not depend on which reactions 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--

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