The standard enthalpy change for the reaction 3 O2(g) → 2 03(g) is 285.4 kJ mol·' at 298 K and 1 bar. The heat capacity of O2(g) and O3(g) at constant pressure are 29.4 J K-' mol' and 38.2 J K-' mol-'. Assuming that the heat capacities do not change over this temperature range, calculate the enthalpy if reaction at 380 K. [284.4 J mol·' ]
