What volume of oxygen at STP is required to effect complete combustion of 200cm³ of acetylene and what would be the volume of carbon dioxide formed?

Solution

2C₂H₂ + 5O₂ -------> 4CO₂+ 2H₂0

2vol 5vol 4vol 2vol

2vol of C₂H₂ uses 5vol of O₂for combustion
Therefore, 200cm³ of C₂H_{2 =}5 x 200/ 2
= 500cm³

By Gay Lussac's law 2vol of C₂H_{2 =}4vol of CO₂

Thus, 200cm³of C₂H₂ = 4 x 200/2
= 400cm³of CO₂ at STP
