Calculate the heat of formation of water from its constituent elements from the following information:

Question

3 H2 (g) + O3 (g) �¨ 3H2O ∆H = ?
2 H2 (g) + O2 (g) �¨ 2H2O ∆H = - 483.6
3 O2 (g) �¨ 2O3 (g) ∆H = 284.5
a. -480 kJ/mol b. 480 kJ/mol c. -867 kJ/mol d. 867 kJ/mol

Answer 1

I partially answered this about an hour ago. The question makes no sense. There is a delta H by the equation for the formation of water from its constituent parts. The equation with the question marks is not th formation of water form its constituent parts.
