1. Sulfur dioxide (SO2) can react with O2 to form sulfur trioxide (SO3). A gas stream having the composition (in mole percentage) shown in the figure below is to be passed through a two-stage converter to produce SO3. The single-pass fractional conversions of SO2 to SO3 are 0.80 in stage 1 , and 0.50 in stage 2, respectively. To boost the overall fractional conversion of SO2 to 0.98, part of the exiting gas from stage 2 is recycled back to the inlet of stage 1 . Calculate the molar ratio of stream 6 to stream 1
