(k) Exothermic &endothermic reaction ​

Answer 1

Answer:

Exothermic reaction it releases the heat , causing the temperature of the immediate surroundings to raise.

Endothermic reaction itabsorbs the heat and it keeps the surroundings cool.

Answer 2

$Answer⤵️☺$

Exothermic reactions are those reactions in which heat is released.

Reactants→products+heat

For example, formation of ammonia from nitrogen and hydrogen is an exothermic reaction.

N²(g)+3H²(g)→2NH³(g)+92.2kJ

Endothermic reactions are those reactions in which heat is absorbed.

Reactants+heat→products

For example, dissociation of ammonia into nitrogen and hydrogen is an endothermic reaction.

2NH³(g)+92.2kJ→N²(g)+3H²(g)
