A binary feed mixture containing equimolar quantities of components S and T is to be distilled in a fractionating tower at atmospheric pressure. The distillate contains 96 mol % S. The q-line (feed line) intersects the equilibrium line at
x′ = 0.46 and y′ = 0.66, where x′ and y′ are mole fractions. Assume that the McCabe–Thiele method is applicable and the relative volatility is constant.
The feed is
The feed is
Correct : b
