Q1: Pick out the wrong statement.

ANS:C - Heat removal load on cooler remains constant, even with increase of the reflux ratio in a distillation column.

The wrong statement is: "Total condenser or reboiler is considered equivalent to one theoretical plate in McCabe-Thiele method of theoretical plate calculation for distillation column." In the McCabe-Thiele method, a total condenser or reboiler is not considered equivalent to one theoretical plate. Instead, these components are considered as either a reflux or a feed condition. A total condenser represents the maximum reflux condition, while a reboiler represents the minimum reflux condition. Each theoretical plate corresponds to a stage of vapor-liquid equilibrium in the column, where separation of components occurs.
