If the Standard Reaction Enthalpy for the Reaction
NO₂(g) $\rightarrow$ NO(g)+ O(g)
Is Needed,Calculate It from the Standard Enthalpy of NO(g)

If the standard reaction enthalpy for the reaction
NO₂(g) $\rightarrow$ NO(g) + O(g)
Is needed,Calculate it from the standard enthalpy of formation of ozone,+142.7kJ.mol^-1 ,And from the reactions listed below:
O₂(g) $\rightarrow$ 2O(g)
$\Delta$ H° = +498.4 kJ.mol^-1
NO(g) + O₃(g) $\rightarrow$ NO₂(g) + O₂(g)
$\Delta$ H° = -200 kJ.mol^-1

A) +355 kJ.mol^-1
B) +555 kJ.mol^-1
C) +192 kJ.mol^-1
D) +592 kJ.mol^-1
E) +306 kJ.mol^-1
