Question

Identify the endothermic and exothermic reaction.
a. $H C l + N a O H \to N a C l + H_{2} O + h e a t$
b. $2 K C l O_{3} (s) Δ - \to 2 K C l (s) + 3 O_{2} ↑$

Open in App

Solution

(a) $H C l + N a O H ⟶ N a C l + H_{2} O + h e a t$
it is neutrilisation reaction and neutrilisation reactions are exothermic,
(b) $2 K C l O_{3} (s) + h e a t ⟶ 2 K C l + 3 O_{2} (g)$
Energy is require to break the bonds of $K C l O_{3}$ , it is endothermic reaction.
