The bond in molecular iodine is quite weak, and hot iodine vapor contains a proportion of atoms. When 1.00 g of I2 is heated to 1000 K in a sealed container of volume 1.00 L, the resulting equilibrium mixture contains 0.830 g of I2. Calculate K for the dissociation equilibrium I2(g) ? 2 I(g). The atomic weight of I is 127.
Calculate the rate of Fe2 O3 production (kg/min) in the outlet solid stream, and the total molar flow and composition of the outlet gas stream.
