1. Write an equilibrium expression

e.g. aA + bB $\rightleftharpoons$ cC + dD 

$K_{fwd}=\dfrac{[C]^c*[D]^d}{[A]^a*[B]^b}$

(don't include solids, or water)

2. Make an I.C.E. (initial, change, equilibrium) and use [CO] given at eq. to find $[CO_2]$.

3. Plug in your values into the equilibrium expression and solve.
