Homework Help: Chemistry

Posted by Ezra on Friday, March 22, 2013 at 12:42pm.

The value of Kc for the reaction below is 1.6
C(s)+CO2(g)=2CO(g)
What is the equilibrium concentration of CO when [CO2]=.50M?
The usual ICE table doesn't work for me.

C(s)+CO2(g)=2CO(g)
I - 0
C -x +2x
E .50 +2x

1.6=[2x]^(2)/(.50)
That's how I did it but the answer is .89 and I didn't get that.
