4. Acrylonitrile is produced in the reaction of propylene, ammonia, and oxygen: C3H6+ NH3 + 3/2 02 → C3H3N+3 H₂O The feed contains 10.0 mole% propylene, 12.0% ammonia, and 78.0% air. A fractional conversion of 30.0% of the limiting reaction is achieved. Taking 100 mole 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 30% conversion of the limiting reactant.
