## Chemistry and Chemical Reactivity (9th Edition)

a) The concentration of CO is $1.0\ mol\div 200.0\ L=0.005\ M$, and of CO2 is $0.20\ mol\div 200.0\ L=0.001\ M$ The equilibrium constant is given by: $K=[CO]^2/[CO_2]$ $K=(0.001\ M)^2\div0.005\ M=0.0002$ b, c) It would be the same, the concentration of solids isn't computed in the equilibrium constant.
