The heat of formation of a substance is defined as the heat change when one mole of the substance is formed from its constitute elements in their standard states.
The standard state of FeSO₄ is (s), and the constitute elements of FeSO₄ are:
Iron, and its standard state is (s)
Sulfur, and its standard state is (s)
Oxygen, and its standard state is (g)
Hence, the equation for the heat of formation of FeSO₄ is :
S(s) + Fe(s) + 2O₂(g) → FeSO₄(s)
...... The answer is : d) S(s) + Fe(s) + 2O₂(g) → FeSO₄(s)
