I'm really focused on getting an explanation with this so I can do the rest of them, so if you could explain and answer that would be great.
Given the following thermochemical equations,
NO(g) + O3(g) → NO2(g) + O2(g) where Δ H = −198.9 kJ/mol
O3(g) → 3 2 O2(g) where Δ H = −142.3 kJ/mol
O2(g) → 2O(g) where Δ H = +495 kJ/mol
Determine the enthalpy change for the reaction: 2NO2(g) → 2NO(g) + O2(g)
