Question

The enthalpy changes for the following processes are listed below: Cl_2(g) = 2Cl(g), 242.3 kJ mol^ -1 ; I_2(g) = 2I(g), 151.0 kJ mol^ -1 ; ICl(g) = I(g) + Cl(g), 211.3 kJ mol^ -1 ; I_2(s) = I_2(g), 62.76 kJ mol^ -1 . Given that the standard states for iodine and chlorine are I_2(s) and Cl_2(g), the standard enthalpy of formation for ICl(g) is
