Question

Calculate the standard enthalpy change for the sublimation of iodine, given that the sublimation of 1 mole of iodine requires 62.44 kJ of energy and the standard enthalpy of formation of iodine (s) is 0 kJ/mol.

Answer 1

The standard enthalpy change for the sublimation of iodine can be calculated using the given information. Since the standard enthalpy of formation of iodine  s  is 0 kJ/mol, we can directly use the energy required for the sublimation of 1 mole of iodine as the standard enthalpy change for the sublimation process.Standard enthalpy change for sublimation of iodine = 62.44 kJ/molTherefore, the standard enthalpy change for the sublimation of iodine is 62.44 kJ/mol.
