9.28 A bed of 2 moles of chromium metal containing some chromium oxide is held at 800oC while moist argon at 1 atm pressure flows through it. The purpose of the apparatus is to remove water vapor from the inert gas. The inlet water vapor mole fraction is 0.016.

(a) What is the mole fraction of water vapor in the exit gas?

(b) What is the heat removal/addition rate required to maintain the bed temperature?

If the argon flow rate is 0.01 moles/s, how long will the bed be able to remove water vapor?
