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,+142.7 kJ.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
