Phosgene is produced in the reaction of carbon monoxide with chlorine gas:
CO( g ) + Cl₂( g ) → COCl₂( g )
What is the theoretical yield of phosgene if 0.767 moles of CO reacts with excess Cl₂ gas?

Question

Quizplus · Accepted Answer

The balanced equation shows that 1 mole of CO reacts with 1 mole of Cl2 to produce 1 mole of COCl2. Therefore, 0.767 moles of CO will react to produce 0.767 moles of COCl2. The molar mass of COCl2 is 98.92 g/mol, so the theoretical yield is 0.767 moles * 98.92 g/mol = 76.0 g.
