When iodine and chlorine are reacted we get solid 2ICl and enthalpy change of this reaction is +14kJmol, when the solid 2ICl is reacted chlorine gas we get 2ICl3 and enthalpy change of this reaction is -88kJmol, how do I draw the energy cycle and then calculate enthalpy change of formation of 2ICl3?
