1 Answer

Answer :

For a start, your equation isn’t balanced; it should be Cl2 (Cl2, not 2Cl, because of HONClBrIF). Given this, if we assume the reaction goes to completion, 1.5 mol Cl2 will produce 1.5 mol COCl2. Now you just want the percent that was produced compared to the theoretical maximum that I just stated. So, .8/1.5*100=53.3% Incidentally, is that supposed to be CO or Co? It has no effect on the calculation, just curious.
