The following statement has to be justified. “Exothermic reactions are spontaneous but endothermic reactions are nonspontaneous.” Concept Introduction: Spontaneous process has positive entropy value and negative free energy, enthalpy value. Non-spontaneous process tends to proceed with negative entropy value and positive free energy and enthalpy. A reaction which proceeds with absorption of heat is called endothermic reaction whereas a reaction which proceeds with release of heat is called exothermic reaction .
