Calculate the volue of `O_(2)` at 1 atm and 273 K required for the complete combustion of 2.64 L of acetylene `(C_(2)H_(2))` at 1 atm and 273 K. `2C_(2)H_(2)"(g)"+5O_(2)"(g)"rarr4CO_(2)"(g)"+2H_(2)O(l)`

A

3.6 L

B

1.056 L

C

6.6 L

D

10 L

Text Solution

Verified by Experts

The correct Answer is:
c
(c) `n_(c_(2))H_(2)=(PV)/(RT)=(1xx2.64)/(0.0821xx273)=0.118"mole"`
`n_(O_(2))=(5)/(2)xx0.118=0.294`
`V=(nRT)/(P)=6.6L`
