2. Nitric acid, which is among the top 15 chemicals produced in the United States, was first prepared over 1200 years ago by heating naturally occurring sodium nitrate (called saltpeter) with sulfuric acid and collecting the vapors produced. Calculate AHa for this reaction. AH: [NANO;(s)] =-467.8 kJ/mol; AHºg [NaHSO,(s)] =- 1125.5 kJ/mol; AH: [H,SO,(I) =-814.0 kJ/mol; AH: [HNO3(g)] =-135.1 kJ/mol NaNO3(s) + H,SO,(1) → NAHSO,(s) + HNO;(g)

2. Nitric acid, which is among the top 15 chemicals produced in the United States, was first prepared over 1200
years ago by heating naturally occurring sodium nitrate (called saltpeter) with sulfuric acid and collecting the
vapors produced. Calculate AHa for this reaction. AH°: [NANO;(s)] = -467.8 kJ/mol; AH: [NAHSO,(s)] =
1125.5 kJ/mol; AH: [H,SO,(1) =-814.0 kJ/mol; AH [HNO;(g)] =-135.1 kJ/mol
NaNO3(s) + H,SO,(1) → NaHSO,(s) + HNO3(g)
