Question
Set up a Hess's law cycle, and use the following information to calculate AH, for aqueous nitric acid, HNO,taq). You will need
to use fractional coefficients for some equations. Hint: AH, involves the formation of 1 mol of substance in its standard state, from its
constituent elements in their standard states.
3NO:(9) + H,O()
2NO(G) + 0:(9) -
- 2HNO,(aq) + NO(9)
AH =-131 kJ
2NO, (9)
4NHS(9) +50,(g)4NO(9) +6H,0(1)
|용0:(9) + Hs(9)→ Hs0(0)
AH= 119 kJ
-
AH = 1,164 kJ
AH,
=-254 kJ/mol
Na (9) +H:(9) NH,(9)
AH,
-53 kJ/mol
