प्रश्न

Ethane burns in oxygen to form CO2 and H2O according to the equation:

`2C_2H_6+7O_2 -> 4CO_2 + 6H_2O`

If 1250 cc of oxygen is burnt with 300 cc of ethane.

Calculate:

1) the volume of `CO_2` formed

2) the volume of unused `O_2`

उत्तर

So, ethane is limiting reagent.

1) 2 x 22400 cc ethane give -> 4  x 22400 cc `CO_2`

∴ 300 cc ethane given → `(4xx22400xx300)/(2xx22400) "cc" Co_2` 

= 600 cc CO2

2) For 300 cc Ethane 1050 cc of O2 will be required.

So unused O2 is (1250-1050) = 200 cc
