Which of the following set of equations could be used to represent the standard enthalpy of formation of glucose?
a
6C (s) + 6H 2(g) + 3O2(g) → C 6H12O6(s)
b
6CO2(g) + 6H2O (l) → C6H12O6(s) + 6O 2(g)
c
6C(g) + 6H 2(g) + 3O2(g) → C6H12O 6(s)
d
6C(g) + 6H 2(g) + 3O2(g) → C 6H 12O 6(aq)

It is the enthalpy change when 1 mole of a compound is formed from its elements in their standard states.
🧠 Standard states:
Carbon → C(s, graphite)
Hydrogen → H₂(g)
Oxygen → O₂(g)
🧪 Formation of glucose:
Glucose formula: C₆H₁₂O₆
So we form it from:
6C(s)
6H₂(g)
3O₂(g)
Answer should be A
