Response:

There are two types of process classified on the heat flow

!) exothermic process

2) endothermic process

if heat flows into the system it is called endothermic process

if heat flows out of the system it is called exothermic process

In endothermic process the change in heat energy i.e ΔH is -ve

In exothermic process the change in heat energy i.e ΔH is +ve (where ΔH = Hp - Hr)

Hp is the heat content of products and Hr is the heat content of reactants
