1. The problem statement, all variables and given/known data What is the enthalpy ΔH, when 1 mole of water is heated at 101 kPa from 353 K to 393 K? Outline the process in an H (T) diagram. The following values are available: Cp (H2O, l) = 75.0 J K-1 mol-1; ΔHvap = 47.3 kJ mol-1 at 373 K; Cp (H2O, g) = 35.4 J K-1 mol-1 2. Relevant equations 3. The attempt at a solution I tried to solve this: Is this the right way?
