What concentration of `CO_2` be in equilibrium with `2.5 xx 10^(-2) "mol litre"^(-1)` of `CO `at `100^@C` for the reaction
`FeO_((s)) + CO_((g))

A

`1 xx 10^(-4)`

B

`2.5 xx 10^(-2)`

C

`5 xx 10^(-2)`

D

`12.5 xx 10^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`because K_c = ([CO_2])/([CO]) implies 5 = ([CO_2])/(2.5 xx 10^(-2))`
`implies [CO_2] = 5 xx 2.5 xx 10^(-2) = 12.5 xx 10^(-2)`
