Question
Calculate ΔH° in kilojoules for the following reaction, the preparation of the unstable nitrous acid, HNO2.
Use the following thermochemical equations:

Transcribed Image Text:1) 2NACI() + H0(1) 2HCI(g) + Na,O(s)
AH° = +507.31 kJ
2) NO(g) + NO,(g)+ Na,O()-
+ 2NANO2()
AH° = -427.14 kJ
3) NO(g) + NO,lg) N,0(g) + O,(g)
AH° = -42.68 kJ
!!
4) 2HNO;(1) → N2O(g) + O2(g) + H,O(1)
AH° = +34.35 kl
