When a certain amount of ethylene was combusted, 6226 kJ heat was evolved. If heat of combustion of ethylene is 1411 kJ, the volume of `O_2` (at NTP) that entered into the reaction is

A

296.5 ml

B

296.5 litre

C

`6226xx22.4` litre

D

22.4 litre

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(2)H_(4)+3O_(2)rarr 2CO_(2)+2H_(2)O , Delta H=-1411 kJ`
1411 kJ heat is produced by 3 mol `O_(2)` so 6226 kJ heat is produced by -
`(3)/(1411)xx6226xx22.4=296.5` litre.
