Nitric аcid, which is аmоng the tоp 15 chemicаls prоduced 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 ΔH°rxn for this reaction. ΔH°f [NaNO3(s)] = –467.9 kJ/mol ΔH°f [NaHSO4(s)] = –1125.5 kJ/mol ΔH°f [H2SO4(l) = –814.0 kJ/mol ΔH°f [HNO3(g)] = –133.9 kJ/mol NaNO3(s) + H2SO4(l) → NaHSO4(s) + HNO3(g) Write out your calculations and answers clearly, with all numbers labeled correctly, on a piece of paper.
