Question

Calculate the standard enthalpy change for the fusion of solid hydrogen (H₂) at its melting point of 13.81 K, given that the standard enthalpy of fusion of H₂ is 0.117 kJ/mol.

Answer 1

The standard enthalpy change for the fusion of solid hydrogen  H  at its melting point can be calculated using the given standard enthalpy of fusion. In this case, the standard enthalpy of fusion is already provided as 0.117 kJ/mol.Therefore, the standard enthalpy change for the fusion of solid hydrogen  H  at its melting point of 13.81 K is 0.117 kJ/mol.
