Enthalpy is the heat content of a chemical system
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.

What is the different between enthalpy and enthalpy change?
The enthalpy is the total kinetic and potential energy within a chemical system. A change in enthalpy is the difference between the enthalpy of the products and the enthalpy of reactants.
What is the enthalpy of HDPE?
enthalpy LDPE
How do you calculate enthalpy given the temperature?
Enthalpy of a chemical species is expressed in joules/mol. No temperature unit is included in enthalpy and thus temperature does not play a role in its calculation. change in enthalpy = enthalpy of reactants - enthalpy of products enthalpy values of chemical species can be found in a merck index
What is dimension of enthalpy?
Specific enthalpy has the same dimension as energy or mass. Enthalpy of a system is the mass of a system\ multiplied by the specific enthalpy of that system.
What is positive enthalpy change?
enthalpy change of formation

What is relation between hydration energy lattice energy and enthalpy of solution?
enthalpy change of solution=enthalpy change of hydration - enthalpy change of lattice
What is positive enthalpy change?
enthalpy change of formation
How do you calculate a value for the enthalpy change?
The change in enthalpy (∆H) is the enthalpy of the products - the enthalpy of the reactants. Under conditions of constant pressure, ∆H = q (heat).
How is the enthalpy of reaction related to the enthalpies of formation for the products and reactants?
The difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
What is the difference between enthalpy change and molar enthalpy?
enthalpy change is for a specific quantity of reagent (eg. in grams). Molar enthalpy change is for the number of moles in the balanced equation
What is enthalpy of dissociation?
A short explanation is: it is the standard enthalpy of dissociation by homolysis.
How does a catalyst affect the enthalpy change of a reaction?
It does not change the enthalpy of a reaction.
How do you make a sentence for enthalpy?
Enthalpy is a thermodynamic property of a thermodynamic system.
