Question

What is the difference between enthalpy of formation and bond enthalpy?

Answer 1

The bond enthalpy and enthalpy of formation will be discussed in the given question, and the bond enthalpy and enthalpy of formation will be differentiated. Both of them are used to describe a bond. Both of them need a lot of energy.

Complete Step By Step Answer:
The typical reaction enthalpy for the production of a compound from its elements (atoms or molecules) at the given temperature $(298.15K)$ and pressure ( $1{\text{ }}bar$ ) in their most stable reference states is called enthalpy of formation.
Enthalpies (or temperatures) of formation are extremely important in calculating reaction enthalpies. This is because any reaction may be viewed as taking place along a path in which all reactant compounds are first changed to elements, and then all elements are converted into the substance's compounds.
The amount of energy necessary to break or form a bond is referred to as bond enthalpy.
The idea of a complete change in the energy of the system is given by the combined bond enthalpy for all broken and produced bonds during the process, which is called change in enthalpy.
The reaction is either endothermic or exothermic depending on whether the change in enthalpy is positive or negative.

Note:
The enthalpy of formation is a measure of a substance's stability. Bond enthalpies are a measure of an individual bond's strength that can be used to estimate $\Delta H$ in calculations. If everything we are working with is in a gaseous state, you can calculate bond enthalpy directly. If it is in a liquid condition, it will require additional energy to convert it to a gaseous state.
