How is ammonia only oxidised in this?Watch
4NH3(g) 5O2(g) ⇌ 4NO(g) 6H2O(g) ∆H –905 kJ mol–1
In terms of redox, state what happens to the ammonia in the forward reaction.
The nitrogen in NH3 goes from an oxidiation state of -3 to +2
The hydrogen in NH3 goes from an oxidation state of +3 to +1.
So how am I meant to tell whether ammonia is oxidised or reduced ??
Since NH3 is a reducing agent,it gets oxidised
The hydrogen in NH3 is without any change in the oxidation state.
4NH3(g) + 5O2(g) ⇌ 4NO(g) + 6H2O(g)
NH3 is a reducing agent and oxygen gas is an oxidizing agent and the oxygen is reduced by NH3 from 0 to -2.
