Two reactions are given below :
(i) `2KI + Cl_(2) to 2KCl + I_(2)`
(ii) `2K + Cl_(2) to 2KCl`
identify the type of reaction giving justification in each case.

Explanation

(i) It is an example of displacement reaction. Since `Cl_(2)` is more reactive than `I_(2)`, it displaces the same from KI solution. Violet fumes of iodine appear from the tube.
(ii) It is an example of addition reaction. The compound KCl contains both K and Cl as its constituents.
