Is the enthalpy change of the chemical reaction between a monoprotic acid and sodium hydroxide the same for all strong monoprotic acids?

The reaction that occurs between a strong monoprotic acid and sodium hydroxide is H++OH- => H2O. This reaction is the same for all strong monoprotic acids and sodium hydroxide so, in theory, they should all have the same standard enthalpy of reaction. In practice, there are very slight differences between acids. If you are in a freshman or sophmore chemistry class, say yes. If you are in physical or analytical chemistry say no.

What is a correct description of enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Does the overall enthalpy change of a chemical reaction depend on the reaction pathway?
Absolutely not.
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.
What does the enthaply of reaction measure?
The enthalpy of reaction is the change of the system enthalpy after a chemical reaction.

will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
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.
Does the overall enthalpy change of a chemical reaction depend on the reaction pathway?
Absolutely not.
What kind of enthalpy change favors a spontaneous reaction?
An exothermic reaction is a chemical reaction that releases energy in the form of heat. It favors a negative enthalpy change.
How is Hess's law applied in calculating enthalpy?
All the reactions in a path are added together.
Would the enthalpy change be different if solid sodium hydroxide pellets were added to hydrochloric acid instead of adding hydrochloric acid to sodium hydroxide solution?
Yes, the reaction involving the solid is actually an individual step in the equation of the reaction between the solutions. If you were to add the change in enthalpy of the reaction with the solid NaOh to the change in enthalpy of the other step in the reaction (that's adding water and the NaOh pellets) you would find the sum equivalent to the change in enthalpy of the reaction involving the two solutions (this is supported by Hess's law). I suggest that you consider Hess's law for more information.
The enthalpy change for a chemical reaction exactly as it is written is what?
The amount of energy that is lost or gained by the products during the reaction.
