Calculate the entropy change when 4.44g of H2 reacts with O2 according to the reaction

2H2(g) + O2(g)→2H2O(ℓ)

at 298 K and 1 atm pressure. The stan-

dard molar enthalpy of formation of H

2O(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
