Homework Help: Chem

Posted by Katie on Sunday, March 21, 2010 at 8:00pm.

Consider this reaction: CO (g) + H2O (g0 <---> CO2(g)+H2(g)

kc=102 at 500 K

A reaction mixture initially contains 0.145 M of CO and 0.145 M of H20. What would be the equilibrium concentration of [CO]?

I so far have
kc= [H2][CO2]/[CO][H2O]= 102

I know i have to set up an ice table so i have:
CO H2O CO2 H2
I 0.145 M 0.145M 0 0

C -x -x +x +x

E

what do i do now? i'm kind of stuck. thank you!
