Describe the relationship between a compound’s stability and it’s enthalpy of formation

Enthalpy of formation and its stability is described below.

Explanation:

The higher the entropy, the larger amount of available states. Edit: Enthalpy of formation refers to the energy involved in the formation of a substance from its elements in their most stable forms. Higher enthalpy means heat had to be absorbed to form the substance, which makes the substance a higher-energy compound.Enthalpy of formation refers to the energy involved in the formation of a substance from its elements in their most stable forms. Higher enthalpy means heat had to be absorbed to form the substance, which makes the substance a higher-energy compound. High energy compounds tend to be more reactive, therefore less stable. The reverse is true for lower enthalpies.The reaction enthalpy is the heat given off or taken up for the rxn, i.e., the enthalpy difference between the reactants and products. The enthalpy of formation of a compound is the enthalpy change between the elements in their standard state (reactants) and the compound (product).

The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance.
