Chrome ore is a combination of iron and chromium oxides, feo. cr2o3. the ore is reacted with soda ash* and oxygen from air at 1000°c to produce soluble sodium dichromate, which can then be dissolved out leaving an insoluble residue. a simplified reaction mechanism is shown below. 4fe0.cr203+8na2 co3 + 702 > 8na2cro4+ 2fe203 + 8co2 solid solid solid solid gas gas discuss the factors affecting reactor choice. determine the most suitable reactor for the process, fully justifying your choice. [5] note: soda ash melts at 851°c and softens in the 650-700 c range fthulono
