If the heat of formation of H2O(l) is –286 kJ/mol, which
of the following thermochemical equations is correct?
(a) 2 H(g) + O(g) H2O(1)
AH = -286 kJ
(b) 2 H2(g) + O2(g) 2 H2O(1)
AH = -286 kJ
(c) H2(g) + 3 02(8) H2O(0
AH = -286 kJ
(d) H2(g) + O(g) →→ H2O(g)
AH = -286 kJ
(e) H2O(1) H2(g) + 2 02(8)
AH = -286 kJ
