A binary distillation column is operating with a mixed feed containing 20 mol% vapour. If the feed quality is changed to 80 mol% vapour, the change in the slope of the q-line isA homogeneous reaction (R ® P) occurs in a batch reactor. The conversion of the reactant Ris 67% after 10 minutes and 80% after 20 minutes. The rate equation for this reaction is
Suppose that for mass transfer of species A from a fluid flowing over a flat plate the Schmidt number is much less than one (Sc
