H < 0 contributes to spontaneity.
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 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 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 difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
The enthalpy of reaction is the change of the system enthalpy after a chemical 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 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 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 reaction does not depend on the intermediate reactions.
The enthalpy of a reaction does not depend on the reactant path taken.
Enthalpy is the measurement of total energy change of a reaction. The energy of bond formation and bond breaking can be used to calculate the bond enthalpy of the reaction. Bond enthalpy is the enthalphy change when 1 mol of bond is broken. Therefore the general equation to calculate the enthalpy change is energy of bond broken subtract by energy of bond formation.
It tells if the reaction will process spontaneously or not
C - The enthalpy of reaction does not depend on the steps taken in the reaction. APEX --WXM--
