A container holds 10kg of liquid water and 7kg of water vapour at 140°C. The water is heated at constant pressure until all the liquid is evaporated Calculate the enthalpy (kJ/kg) at the end of the process

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
