Solution
\[\ce{4NH3 + 5O2 ->[Platinum 800^\circ C] 6H2O + 4NO}\]
- The catalyst used is platinum or platinum-rhodium gauze.
- The catalyst glows red hot because ammonia oxidation is highly exothermic and releases a large amount of heat.
- The industrial process that begins with this reaction is the Ostwald process, used to manufacture nitric acid.
