30 kmol/h . Assume that the mole fraction of acetone in the air (  ‐phase)

 

entering the system is specified as ( y )  0 . 010 and assume that the mole A 6

fraction of acetone in the water ( ‐phase) entering the system is specified as ( x )  0 . Given that there are 5 equilibrium stages, reconstruct Figure 5.10a, A o

and use the reconstructed figure to determine ( y ) .
