Question

Determine ΔH for the third reaction from the information given.

1/2 N₂(g) + O₂(g)	↔ NO₂(g)	ΔH = 33.85 kJ
N₂(g) + 2 O₂(g)	↔ N₂O₄(g)	ΔH = 9.700 kJ
2 NO₂(g)	↔ N₂O₄(g)	ΔH = ?

Expert Solution

Step 1

The two reactions given are,

$1) 1 / 2 N_{2} (g) + O_{2} (g) \leftrightarrow N O_{2} (g) Δ H = 33.85 K J 2) N_{2} (g) + 2 O_{2} (g) \leftrightarrow N_{2} O_{4} (g) Δ H = 9.700 K J$
