Which of the following is a combination and which is a displacement reaction ?

(a) $C l_{2} + 2 K I ⟶ 2 K C I + I_{2}$

(b) $2 K + C I_{2} ⟶ 2 K C I$

2 K I + C l_{2} \to 2 K C l + I_{2}

C l_{2} + 2 K I \to I_{2} + 2 K C l

Two chemical reactions are as follows:

1. 2KBr (aq)+Cl₂ $\to$ 2KCl (aq)+Br₂(aq)

2. Fe (s)+S (s) $\to$ FeS(s)

Identify the two reactions as a combination or displacement reaction.
