Question
If 240 g of carbon is taken in a container to convert it completely to CO2 but in industry it has been found that 280 g of CO was also formed along with CO2. Find the mole percentage yield of CO2. The reactions occurring are C + O2 → CO2 ; C + 
O2 → CO
O2 → COOptions
A.25 %
B.50 %
C.75 %
D.100%
Solution
C + O2 → CO2 + CO
POAC on ′C′ atom
1 (mole of C) = 1 (mole of CO2) + 1 (mole of CO)
= mole of CO2 + 
Mole of CO2 = 20 - 10 = 10
Mole % of CO2 =
×100 = 50%.
POAC on ′C′ atom
1 (mole of C) = 1 (mole of CO2) + 1 (mole of CO)
= mole of CO2 + Mole of CO2 = 20 - 10 = 10
Mole % of CO2 =
×100 = 50%. Create a free account to view solution
