The enthalpy of a chemical reaction is the change of heat during this reaction.
This enthalpy of reaction is 560 joules, for liquid water at 25 oC.
A catalyst does not affect the enthalpy change of a reaction. It speeds up the reaction by providing an alternative pathway with a lower activation energy, allowing the reaction to proceed faster. The overall enthalpy change (ฮH) remains the same with or without a catalyst.
The amount of energy that is used or released as heat in a 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 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 enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a reaction does not depend on the intermediate reactions.
This enthalpy of reaction is 560 joules, for liquid water at 25 oC.
The enthalpy of a reaction does not depend on the reactant path taken.
A catalyst does not affect the enthalpy change of a reaction. It speeds up the reaction by providing an alternative pathway with a lower activation energy, allowing the reaction to proceed faster. The overall enthalpy change (ฮH) remains the same with or without a catalyst.
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.
Its value does not depend on which reactions are added.
... Intermediate equations with known enthalpies are added together.
The enthalpy of reaction measures the amount of heat absorbed or released during a chemical reaction at constant pressure. It indicates whether a reaction is exothermic (heat is released) or endothermic (heat is absorbed).
