Consider a feed stream consisting of three components and flowing at 1mol/min as in the following figure. The stream is separated into two streams D and R. 8 All choices specify three process variables, but some combinations are not sufficient to determine the values of all remaining process variables. Which of the following combinations of process variables, if known, would provide sufficient knowledge to solve for the values of all other process variables? D. yA and xB D,R, and YA YA0YB. and YC D. YA, and XA yA,xA and xC xA,,xB, and yA D. yA and yB R. YA and xC
