500 kg/h of steam drives a turbine. The steam enters the turbine at 44 atm and 450 oC at a linear velocity of 60 m/s and leaves at a point 5 m below the turbine inlet at atmospheric pressure and a velocity of 360 m/s. The turbine delivers shaft work at a rate of 70 kW and the heat loss from the turbine is estimated to be 11.6 kW. Calculate the specific enthalpy change associated with this process.
You are told that K=3.76x10^-5 for I2(g)=2I(g) at 1000K. You begin an experiment by injecting 1.00 mole of I2 into a 2.00 liter box at 1000K. When the system comes to equilibrium, what will be the concentration of I2 and I in the system at equilib..
