Question
An important step in the synthesis of nitric acid is the conversion of ammonia to nitric oxide. AH°.
[NH,(g)] = -45.9 kJ/mol; AH°, [NO(g)] = 90.3 kJ/mol; AH°, [H,0(g)] = -241.8 kJ/mol
4NH,(g) + 50,(g) → 4NO(g) + 6H,0(g)
Calculate AH°
for this reaction
rxn
Select one:
a. 197.4 kJ
b. 906.0 kJ
c. -105.6 kJ
d. -197.4 kJ
e. -906.0 kJ
