Dari reaksi
2H2(g) + O2(g) → 2H2O(l) ∆H = –572 kJ
dapat dikatakan bahwa...
Kalor pembentukan air adalah –572 kJ
Pembentukan 1 mol air diperlukan 286 kJ
Pada pembakaran 1 mol hidrogen, kalor 572 kJ mengalir dari sistem ke lingkungan
Pada pembentukan 2 mol air, kalor 572 kJ mengalir dari sistem ke lingkungan

Sebanyak 2 mol gas hidrogen jika direaksikan dengan 1 mol gas oksigen akan terbentuk uap air yang membutuhkan kalor sebesar 242 kJ. Persamaan termokimianya adalah ....
H2(g) + 1⁄2O2(g) → H2O(g) ∆H = 242 kJ
2H2(g) + O2(g) → 2H2O(g) ∆H = 242 kJ
2H2(g) + O2(g) → 2H2O(g) ∆H = -242 kJ
2H2O(g) → 2H2(g) + O2(g) ∆H = 242 kJ
