The enthalphy of a reaction does not influence the rate of reaction, it may however influence the rate of the reverse reaction, as we now would have a change in potential energy (for example an exothermic reaction requires more energy to go in the reverse then does an endothermic). This is why you can consider some products thermodynamically favourable - as they are the exothermic product which would require more energy to turn back towards reactants then to stay as products.
Overall rate is not seen in the various rate law or rate of reaction equations utilised such as arrhenius temperature dependance or the rate law equation. Rate is indepedant of enthalpy WRT to forward reaction.
To calculate the enthalpy change of a reaction, subtract the total enthalpy of the reactants from the total enthalpy of the products. This difference represents the enthalpy change of the reaction.
The enthalpy temperature dependence influences the overall energy changes in a chemical reaction by affecting the heat absorbed or released during the reaction. As temperature increases, the enthalpy change also changes, which can impact the reaction's energy balance.
The enthalpy change for the reverse reaction is equal in magnitude but opposite in sign to the enthalpy change for the forward reaction.
The reaction is exothermic, meaning it releases heat. The enthalpy of the reaction is negative, indicating that it is exothermic.
The enthalpy of a reaction is a measure of the heat energy exchanged with the surroundings at constant pressure. A negative enthalpy change indicates an exothermic reaction, where heat is released. A positive enthalpy change indicates an endothermic reaction, where heat is absorbed.
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.

The enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
Catalysts do not change the postition of the reaction's equilibrium. Adding a catalyst will increase the rate of reaction, but it will do this by providing another pathway for the reaction to occur acros, meaning a lower activation enthalpy is needed. :)
The enthalpy change for the reverse reaction is equal in magnitude but opposite in sign to the enthalpy change for the forward reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
The reaction is exothermic, meaning it releases heat. The enthalpy of the reaction is negative, indicating that it is exothermic.
Increasing the temperature the reaction rate increase.
The enthalpy of a reaction does not depend on the reactant path taken.
