(a) The heat evolved upon dissolution of atmospheric ozone into water is determined to be +5 kcal/mol at 298 K. Given that ozone has a Henry’s constant of 9.4 × 10−3 mol/L/atm at 298 K, determine its Henry’s constant at 273 K. Note that the definition of Henry’s constant is for the process air to water. (b) If the atmospheric ozone concentration in a polluted air is 100 ppbv, what is the concentration in equilibrium with a body of water in that region at 298 K? Note that you need to assume no losses of ozone other than absorption into water

Crude oil containing 5.0 mole per cent of gasoline is stripped by running the crude down a columnup which live steam is passed, so that 15 kmol of steam are used/100 kmol of oil stripped. Determinethe number of theoretical plates required to reduce the gasoline content to 0.05 mole per cent, assumingthat the crude oil is non-volatile. The vapour–liquid relation of the gasoline in the oil is given by ye = 44x,where ye is the mole fraction in the vapour and x the mole fraction in the liquid. The temperature ismaintained constant by internal heating, so that steam does not condense in the tower.
