What is the entropy change for the reaction 2 H2 (g) + O2 (2) → 2 H20 ) at 372.2 K and 1.0 atm? The enthalpy of reaction at 298.2 K and 1.0 atm is -572. kJ. The Cp values for H2, O2 and H2O are, respectively, 28.8, 29.4 and 75.3 J K-1 mol-1. (Assume that they are constant over this temperature range.)
