6 gm of carbon is burnt with an amount of air containing 18 gm oxygen. The product contains 16.5 gms CO2 and 2.8 gms CO besides other constituents. What is the degree of conversion on the basis of disappearance of limiting reactant ?
Correct answer: B. 95%
- A. 100%
- B. 95%
- C. 75%
- D. 20%
Explanation
The carbon consumed is 16.5/44 + 2.8/28 = 0.475 mol, while the initial carbon is 6/12 = 0.5 mol. Thus, conversion based on carbon disappearance is 0.475/0.5 = 95%; carbon is the limiting reactant here.
