The standard enthalpy of formation of water liquid is -285.76 kJ at 298 K. Calculate the value of Delta_(f)H^(@) at 373 K. The molar heat capacities at constant pressure (C_(P)) in the given temperature range of H_(2)(g),O_(2)(g)andH_(2)O(l) are respectively 38.83, 29.16 and 75.312JK^(-1)mol^(-1). |
| Answer» Solution :`DeltaH_(373)^(@)(H_(2)O(L))=-284.11kJ` | |
