Given the thermochemical equation.
N₂(g) + O₂(g) → 2NO(g) ΔH = +180.6 kJ
If 7.00g of N₂ will be reacted, 45.2 kJ will be added. (Molar masses: N = 14 g; O = 16 g)

Given the thermochemical equation. N₂(g) + O₂(g) → 2NO(g) ΔH = +180.6 kJ If 7.00g of N₂ will be reacted, 45.2 kJ will be added. (Molar masses: N = 14 g; O = 16 g)

Quizplus · Accepted Answer

The thermochemical equation shows that the reaction is endothermic, meaning that heat must be added to the system for the reaction to occur. Therefore, if 7.00g of N2 will be reacted, 45.2 kJ will be added.
