(i) For FeO.

standard enthalpy of formation will be: -271.96kJ

Since, enthalpy of formation is negative, reaction is exothermic.


(ii) For KOH,

standard enthalpy of formation will be: -430.24kJ

Since, enthalpy of formation is negative, reaction is exothermic.


(iii) For NH4NO3

standard enthalpy of formation will be: -367.5kJ

Since, enthalpy of formation is negative, reaction is exothermic.
