Name the catalyst used in commercial method of preparation of phenol.
If 0.5 mol of BaCl₂ is mixed with 0.2 mol of Na₃PO₄, the maximum number of mole of Ba₃(PO₄)₂ that can be formed is
2 mol of Na3PO4 reacts with 3 mol of BaCl2 to form 1 mol Ba3(PO4)2
∴ 0.2 mol of Na3PO4 reacts with 0.3 mol of BaCl2 to form 0.1 mol Ba3(PO4)2.
Thus,Na3PO4 is limiting reagent here.
