∙ 10y agoThe speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.

∙ 8y agoEnthalpy is one of the factors involved in calculating the Gibbs free energy, which determines the spontaneity of a reaction.
Gibbs free energy change = Enthalpy change - absolute temperature x entropy change.
If the Gibbs free energy change is negative then the reaction is spontaneous. This depends on the balance between enthalpy and entropy changes, and also the temperature. The enthalpy change is negative when the reaction is exothermic, and this obviously favours spontaneity, but it is not sufficient alone.

What kind of changes contribute to spontaneity?
An increase in entropy.
What does the enthaply of reaction measure?
The enthalpy of reaction is the change of the system enthalpy after a chemical reaction.
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 a correct description of the enthalpy of a reaction?
The enthalpy of a reaction does not depend on the intermediate reactions.
How does the Gibbs free energy predict spontaneity?
It tells if the reaction will process spontaneously or not

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.
