Question

Identify and name the type of reaction of the following :
i) 2SO2 + O2 <=> 2SO3
(<=> – reversible reaction )
ii) 4NH3 + 5O2 -----> 4NO + 6H2O
iii) 2KClO3 -----> 2KCl + 3O2
(catalyst – MnO2)
iv) FeCl3 + 3NaOH -----> 3NaCl + Fe(OH)3
v) Cu + FeSO4 -----> no reaction

Answer 1

1.) Combination reaction
2.) Oxidation reaction
3.) Decomposition reaction
4.) Double displacement reaction
5.) Since, Cu is less reactive than Fe, it cannot displacement Fe from its compound which is FeSO4. So, displacement reaction doesn't take place.
