Calculate the standard enthalpy change for the phase transition reaction of solid iodine to iodine vapor using the following information:- Standard enthalpy of fusion of solid iodine = 15.52 kJ/mol- Standard enthalpy of vaporization of iodine = 41.57 kJ/mol- Heat capacity of solid iodine = 54.44 J/mol*K- Heat capacity of

Answer 1

To calculate the standard enthalpy change for the phase transition reaction of solid iodine to iodine vapor, we need to consider the following steps:1. Heating solid iodine from its melting point  386.85 K  to its boiling point  457.4 K .2. Melting solid iodine to liquid iodine.3. Vaporizing liquid iodine to iodine vapor.Step 1: Heating solid iodineH1 = Heat capacity of solid iodine   Boiling point - Melting point H1 = 54.44 J/mol*K   457.4 K - 386.85 K H1 = 54.44 J/mol*K  70.55 KH1 = 3840.842 J/molH1 = 3.840842 kJ/molStep 2: Melting solid iodineH2 = Standard enthalpy of fusion of solid iodineH2 = 15.52 kJ/molStep 3: Vaporizing liquid iodineH3 = Standard enthalpy of vaporization of iodineH3 = 41.57 kJ/molNow, we can calculate the total standard enthalpy change for the phase transition reaction:H_total = H1 + H2 + H3H_total = 3.840842 kJ/mol + 15.52 kJ/mol + 41.57 kJ/molH_total = 60.930842 kJ/molTherefore, the standard enthalpy change for the phase transition reaction of solid iodine to iodine vapor is approximately 60.93 kJ/mol.
