The feed contains 12.0 mol% propylene, 15.0 mol% ammonia, and 73.0 mol% air. A fractional conversion of 40.0% of the limiting reactant is achieved. Taking 100 mol of feed as a basis, determine which reactant is limiting, the percentage by which each of the other reactants is in excess, and the molar amounts of all product gas constituents for a 40% conversion of the limiting reactant.

4.4. (25%) hesh air containing 5.00 mol% water vapor is to be cooled and dehumidified to a water content of 2,50 mol% H20, A stream of fresh air is combined with a recycle stream of previously dehumidified air and passed through the cooler. The blended stream entering the unit contains 3.00 mol%H20. In the air conditioner, some of the water in the feed stream is condensed and removed as liquid. A fraction of the dehumidified air leaving the cooler is recycled and the remainder is delivered (o a room. Taking 100 moJ of dehumidified are delivered to the room as a basis of calculation, calculate the moles of fresh feed, moles of water condensed, and moles of dehumidified air recycled.
