Question
The value of Kc = 4·24 at 800 K for the reaction:

Calculate equilibrium concentration of CO2, H2, CO and H2O at 800K, if only CO and H2O are present initially at concentrations of 0·10M each.
Solution
The reaction is

Initial conc 0.1 M 0.1 M 0 0
At eqm. (0.1 - x)M (0.1 -x)M xM xM
where x mole of each of the product be formed.
Applying law of chemical equilibrium, we have

Putting the values in expression (1), we have
