The molar enthalpy of reaction (Hrxn) is the amount of heat transferred during a reaction. It is reported in kilojoules per mole of reactant. A reaction that produces heat is exothermic and has a negative Hrxn. A reaction that absorbs heat is endothermic and has a positive Hrxn.

enthalpy energy mean the heat content of a matter ,,, and it can be reprsented as
H= m h ,,, where m : the mass of matter and its unit ( kg ) ,,, and h : the specific enthalpy and its unit ( kj / kg )

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.
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.
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!
The driving force of a reaction is the change in?
Enthalpy
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 the enthaply of reaction measure?
The enthalpy of reaction is the change of the system enthalpy after a chemical reaction.
What is the description of the enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
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.
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.
What is the Hess's law?
C - The enthalpy of reaction does not depend on the steps taken in the reaction. APEX --WXM--
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!
Is polymerization endothermic or exothermic?
Exothermic, because the reaction enthalpy must be negative. With polymerization, the entropy decreases. The Gibbs energy has to be negative. Thus negative reaction enthalpy. Gibbs energy = reaction enthalpy - temperature*entropy
What is qrxn the symbol for?
enthalpy of the reaction
