# Problem: Use standard enthalpies of formation to calculate the standard change in enthalpy for the melting of ice. (The ΔH˚f for H2O(s) for is –291.8 kJ/mol{{ m{kJ}}}/{{ m{mol}}}).

###### FREE Expert Solution

We are asked to calculate ΔH˚rxn for standard change for the melting of ice.

H2O(l) → H2O(g)

Note that we need to multiply each ΔH˚f by the stoichiometric coefficient since ΔH˚f is in kJ/mol.

Also, note that ΔH˚f for elements in their standard state is 0.
