Question
Calculate the volume of oxygen at STP required for the complete combustion of 100 litres of carbon monoxide at the same temperature and pressure.
\[\ce{2CO + O2 → 2CO2}\]
Solution
\[\ce{2CO + O2 → 2CO2}\]
2 V 1 V 2 V
2 V of CO requires = 1V of O2
so, 100 litres of CO vol. of O2 = `100/2`
= 50 litres.
