Reference no: EM13885678

The standard enthalpy of formation of H2O(l) at 298 K is 285.8 kJ/mol. Calculate the change in internal energy for the following process at 298 K and 1 atm: H2O(l) yields H2(g)+12 O2(g); delta E= ? (Hint: Using the ideal gas equation, derive an expression for work in terms of n, R, and T.) Show your work and explain how you arrived at the answer.
