Q.

When 20ml of methane and 20ml of oxygen are exploded together and the reaction mixture is cooled to laboratory temperature. The resulting volume of the mixture is

View Answer

Correct choice: B

Explanation:

CH4 + 2O2 → CO2+ 2H2O
1mol Methane reacts with 2mol of Oxygen to give 1mol of CO2
i.e 1 ml of Methane reacts with 2ml of Oxygen to give 1ml of CO2
10m of Methane reacts with 20ml of Oxygen to give 10ml of CO2
Vol. of methane left=10ml, vol of CO2 formed=10ml
Total vol =20ml
