A gas mixture consisting of 65% N and 35% SO, by volume is admitted to an absorption column at a rate of 4500 kg/h. It is contacted with a stream of 50% HSO, flowing counter-current to the gas stream at a rate of 5000 kg/h. The gases leave at 101.3 kPa. Water lost with the exit gases exerts a partial pressure of 25.00 kPa. If the concentrated acid leaving the bottom of the column contained 75.00% HSO, what percent of the entering SO is absorbed and converted to acid? S standit to trylow of arts to rialow on d
