[CO] = 1 mol / 2L = 0.5 M

[

According to the equation:

and by using the ICE table:

CO (g) + H2O (g) ↔ CO2 (g) + H2 (g)

initial 0.5 0.5 0 0

change - X - X + X + X

Equ (0.5-X) (0.5-X) X X

when Kc = X^2 * (0.5-X) ^2

by substitution:

1.845 = X^2 * (0.5-X) ^2 by solving for X

∴X = 0.26

∴ [CO2] = X = 0.26
