Design a distillation column to separate a mixture of acetone and water containing 35% (by mole) acetone with a feed rate of 1000 kg/hr. The desired purity of the overhead product is 99% acetone, and the bottom product should contain no more than 0.5% acetone. The available reflux ratio is 2.5, and the feed is at its boiling point at normal atmospheric pressure. Determine the number of theoretical trays required, the optimum feed tray location, and the reflux and boilup rates needed for the design.

A student wishes to determine the standard reduction potential of an unknown metal electrode in a half-cell. They set up an electrochemical cell using a known standard hydrogen electrode (SHE) as the reference electrode and the unknown metal electrode as the working electrode. A voltmeter is used to measure the potential difference between the two electrodes. The reading is +0.45 V. What is the standard reduction potential of the unknown metal electrode in volts?
