Consider the following chemical reaction which produces nitric oxide from its constituent
N2 (g) + O2 (g) → 2 NO (g) ΔH = 182.6 kJ mol-1
If nitrogen and oxygen were mixed and allowed to react under constant pressure conditions, which of the following statements must be true?
Select as many answers as applicable however points will be deducted for incorrect guesses.
Select one or more:
ΔH = q
The temperature of the surroundings would decrease
This is an endothermic reaction
ΔH = ΔU
The temperature of the surroundings would increase
