Question
Endothermic reaction
✓
Answer
Endothermic reaction: The reaction in which heat is absorbed is called an endothermic reaction.
when $KNO _{3( s )}$ dissolves in water, there is absorption of heat during the reaction and the temperature of the solution falls.
$
KNO _{2( s )}+ H _2 O _{( l )}+\text { Heat } \rightarrow KNO _{3( aq )}
$
