Calculate the standard enthalpy and standard entropy change at 298 K for the following reaction: 2Fe(s) + 3/2O2(g) → Fe2O3(s) Given that the standard enthalpies of formation for Fe(s), O2(g), and Fe2O3(s) are 0 kJ/mol, 0 kJ/mol, and -826 kJ/mol respectively. Also, the standard molar entropy of Fe2O3(s) is 87.4 J/K/mol.

Calculate the heat of adsorption of hydrogen gas on a platinum surface given the initial temperature of the system is 298 K and the final temperature is 330 K. The mass of the platinum surface used is 5 grams, and the amount of hydrogen adsorbed is 0.01 moles. Assume the heat capacity of the system is constant at 25 J/K.
