Calculate the melting point of sodium chloride (NaCl) given that its enthalpy of fusion is 28.9 kJ/mol and its entropy of fusion is 41.3 J/K/mol.

Question 1

Question 2

To calculate the melting point of sodium chloride NaCl , we can use the following equation:Melting point T = Enthalpy of fusion H_fus / Entropy of fusion S_fus Given the enthalpy of fusion H_fus is 28.9 kJ/mol and the entropy of fusion S_fus is 41.3 J/K/mol, we can plug these values into the equation:T = 28.9 kJ/mol / 41.3 J/K/mol First, we need to convert kJ/mol to J/mol:28.9 kJ/mol * 1000 J/1 kJ = 28900 J/molNow, we can plug this value back into the equation:T = 28900 J/mol / 41.3 J/K/mol T 700 KTherefore, the melting point of sodium chloride NaCl is approximately 700 K.
