Answer:

in most of the endothermic reactions the atoms gains electrons from one to another. since the atom gains electrons there is a electron repulsive force between the host and the guest electron . As stability is inversely proportional to electron repulsive force the atom gains energy to attain stability .

The endothermic reaction mostly come under electron affinity

Step-by-step explanation:

hope this helps you

if I am wrong just correct me
