Standard Enthalpy of Formation 🔴 Chemistry for Class 11 

In this Thermodynamics (Chemistry) video in Hindi for Class 11 we explained what standard enthalpy of formation is.
Standard Molar Enthalpy of Formation is defined as the enthalpy change for the formation of one mole of a compound from its elements in their most stable states of aggregation at standard condition (STP).
The most stable states of aggregation :-
Oxygen → O₂
Hydrogen → H₂
Carbon → Graphite
Sulphur → Rhombic Sulphur
