Consider the reaction : 4 NO(2 (g)) + ...

Consider the reaction :
`4 NO_(2 (g)) + O_(2 (g)) to 2 N_(2)O_(5 (g)) , Delta_(r) H = -111 kJ`
If `N_(2) O_(5 (s))` is formed instead of `N_(2)O_(5 (g))` in the above reaction , the `Delta_(r)H` value will be :
(given , `Delta H` of sublimation for `N_(2) O_(5)` is `54 kJ mol^(-1)`)

A

`+54` kJ

B

`+ 219` kJ

C

`-219` kJ

D

`-165 ` kJ
