Problem 84P
Nitric acid, a major industrial and laboratory acid, is produced commercially by the multistep Ostwald process, which begins with the oxidation of ammonia:
Step 1. 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(l)
Step 2. 2NO(g) + O2(g) → 2NO2(g)
Step 3. 3NO2(g) + H2O(l) → 2HNO3(l) + NO(g)
(a) What are the oxidizing and reducing agents in each step?
(b) Assuming 100% yield in each step, what mass (in kg) of ammonia must be used to produce 3.0 × 104 kg of HNO3?
