Q.2 (5.0 Marks) A distillation column with a total condenser and partial reboiler is separating acetone from ethanol. The feed composition is 30 mole % acetone. A distillate composition of 0.9 mole fraction acetone is desired. If the bottom composition is 0.13 mole fraction acetone and the boilup ratio v(bar)/8 = 1.0. Assuming constant molal overflow (CMO) and LIV = 0.80. Find the following: a) Number of equilibrium stages using McCabe-Thiele method b) The optimum feed plate location c) The feed quality (a) d) The equilibrium liquid and vapour composition leaving the fifth stage from the top.

On average, observed mortality rates are higher for people who buy life insurance than for people who do not. This is best taken as evidence in favor of adverse selection in life insurance markets.

Private markets are powerless to combat adverse selection, so the only solution is a government-mandated insurance contract.
