Phosgene is produced in the reaction of carbon monoxide with chlorine gas in the following reaction:
CO( g ) + Cl₂( g ) → COCl₂( g ) .

What is the theoretical yield of phosgene if 0.767 moles of CO react with excess Cl₂gas?

Question

Quizplus · Accepted Answer

The theoretical yield of phosgene is 76.0 g. This is because the mole ratio of CO to COCl2 is 1:1, so 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.
