The value of Kc for the reaction below is 1.6
What is the equilibrium concentration of CO when [CO2]=.50M?
The usual ICE table doesn't work for me.
I - 0
C -x +2x
E .50 +2x
That's how I did it but the answer is .89 and I didn't get that.
I don't get 0.89 either. What I don't know is about the equilibrium. Is that 0.50 quoted for CO2 equilibrium concn or initial concn? I worked it both ways and I obtained 0.80 if the 0.5M CO2 is at equilibrium. If initial then I used
1.6 = (2x)^2/(0.5-x) and obtained 0.29.
