Question

What is the enthalpy change of ionization for a solution containing 0.1 mol of HCl (aq) if 20 kJ of heat is absorbed during the ionization process?

Answer 1

To calculate the enthalpy change of ionization, we need to divide the heat absorbed by the number of moles of the substance.Enthalpy change of ionization  H  = Heat absorbed  q  / Number of moles  n H = 20 kJ / 0.1 molH = 200 kJ/molThe enthalpy change of ionization for the solution containing 0.1 mol of HCl  aq  is 200 kJ/mol.
