Question
The following reaction is an example of a4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g)(i) displacement reaction(ii) combination reaction(iii) redox reaction(iv) neutralisation reaction(a) (i) and (iv) (b) (ii) and (iii)(c) (i) and (iii) (d) (iii) and (iv)
Solution 1
The given reaction is 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g).
This reaction is not a displacement reaction because a displacement reaction involves an element being replaced by another in a compound.
It is also not a combination reaction because a combination reaction involves two or more substances combining to form a single substance, which is not the case here.
This reaction is a redox reaction. In a redox reaction, both reduction and oxidation occur simultaneously. Here, NH3 is being oxidized to NO (nitrogen's oxidation state is increasing from -3 to +2), and O2 is being reduced to H2O (oxygen's oxidation state is decreasing from 0 to -2).
Finally, this reaction is not a neutralisation reaction because a neutralisation reaction involves an acid and a base reacting to form a salt and water, which is not the case here.
So, the correct answer is (iii) redox reaction.
Solution 2
The given reaction is 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g).
This reaction is not a displacement reaction because a displacement reaction involves an element being replaced by another in a compound.
It is also not a combination reaction because a combination reaction involves two or more substances combining to form a single substance, which is not the case here.
This reaction is a redox reaction. In a redox reaction, both reduction and oxidation occur simultaneously. Here, NH3 is being oxidized to NO (losing hydrogen) and O2 is being reduced to H2O (gaining hydrogen).
Finally, this is not a neutralisation reaction because a neutralisation reaction involves an acid and a base reacting to form a salt and water, which is not the case here.
So, the correct answer is (iii) redox reaction. Therefore, none of the given options (a, b, c, d) are correct.
Solution 3
The given reaction is 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g).
This reaction is not a displacement reaction because a displacement reaction involves a single element replacing another element in a compound. In this reaction, no single element is replacing another element in a compound.
This reaction is also not a combination reaction. A combination reaction involves two or more substances combining to form a single substance. In this reaction, multiple substances (NH3 and O2) are reacting to form multiple products (NO and H2O).
This reaction is a redox reaction. A redox reaction involves the transfer of electrons from one substance to another. In this reaction, NH3 is being oxidized (losing electrons) and O2 is being reduced (gaining electrons).
Finally, this reaction is not a neutralization reaction. A neutralization reaction involves an acid reacting with a base to produce a salt and water. In this reaction, there is no acid, base, or salt being produced.
Therefore, the correct answer is (iii) redox reaction.
