Calculate the entropy change when 4.31 g of H2 reacts with O2 according to the reaction
2 H2(g) + O2(g) → 2 H2O(l)
at 298 K and 1 atm pressure. The standard molar enthalpy of formation of H2O(l) at 298 K is −285.8 kJ/mol. The corresponding free energy of formation is −237.2 kJ/mol.
Answer in units of J/K.
