Standard Enthalpy of Formation

Standard Enthalpy of Formation

### Formula:

$$\Delta H_f^\circ=\text{Enthalpy change for formation of 1 mole of compound from its elements in standard state}$$

### Terminologies:

- ΔH_f° → Standard enthalpy of formation.

- Formation → Formation of one mole of a compound from its constituent elements.

- Standard State → Most stable form of an element at standard conditions.

### Usage:

- Used to calculate enthalpy changes of reactions using formation data.
