Mass Transfer As the reflux ratio in a distillation coloumn is increased from the minimum, the Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system ANSWER DOWNLOAD EXAMIANS APP
