Hello all
Given
(a) N2(g) + O2(g) --> 2NO(g) ∆H = + 180. 7 kJ
(b) 2NO(g) +O2(g) --> 2NO2(g) ∆H = -113.1 kJ
(c) 2N20(g) --> 2N2(g) --> O2(g) ∆H = -163.2 kJ
Desired Reaction: N2O (g) + NO2(g) --> 3NO (g)
Can someone please tell me where to start? How do I apply Hess's Law? I know I have to work backwards. However, how do I do this in a systematic way?
Any help is appreciated
Thanks
