Calculate ΔH° in kilojoules for the following reaction, the preparation of the unstable acid nitrous acid, HNO2. (4 marks)
 
HCl(g) + NaNO2(s) –> HNO2(l) + NaCl(s)
 
Use the following thermochemical equations.
 

  1. 2 NaCl(s) + H2O(l) –> 2 HCl(g) + Na2O(s) ΔH° = +507.31 kJ

 

  1. NO(g) + NO2(g) + Na2O(s) –> 2 NaNO2(s) ΔH° = -427.14 kJ

 

  1. NO(g) + NO2(g) –> N2O(g) + O2(g) ΔH° = -42.68 kJ

 

  1. 2 HNO2(l) —> N2O(g) + O2(g) + H2O(l) ΔH° = +34.35 kJ
