When 1 L of `CO_(2)` is heated with graphite, the volume of the gases collected is 1.5L . Calculate the number of moles of CO produced at STP:

A

`(1)/(11.2)`

B

`(28)/(22.4)`

C

`(1)/(22.4)`

D

`(14)/(22.4)`

Text Solution

Verified by Experts

The correct Answer is:
C
`CO_(2)(g)+C(s)rarr2CO(g)`
`1-x 2x`
Total volume `=1-x+2x=1+x=1.5`
x=0.5L
`therefore` Volume of `CO=2xx0.5=1L`
Number of moles of `CO=(1)/(22.4)`
