When a certain amount of ethylene was burnt 622 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

29.62 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`
`28 gm" "rarr 1411 kJ`
`? larr" "622 kJ`
