20 ml of a mixture of co and h2 were mixed with excess o2 an exploded and cooled . Volume contracted is 18ml . At room temperature and one atmospheric pressure determine volume ratio of co and h2 in the original mixture?

2H+ O2 → 2H2O
2 V1 Vnil
2CO+ O2 → 2CO2
2 V1 V2 V
From equations, 2V of H2 reacts with = 1 V of O2
Hence, 20 ml of H2 will react with = 10 ml of O2
So, remaining O2 is 20 - 10= 10 ml
Similarly for 10 ml of CO, the oxygen required is = 5ml
So, remaining O2 is 10 - 5 = 5 ml
∴ The composition of resulting mixture will be 5 ml of Oand 10 ml of CO2.
