Question

The initial concentrations of four species involved in an equilibrium are: [Cl2] = 1.40 M, [HCl] = 0.100 M, [O2] = 0.300 M and [H2O] = 0.500 M.  Is the reaction at equilibrium?  If not, in what direction must the reaction shift for the equilibrium to be reached?  Set up Kc in terms of the initial amounts and x as done in class.  Do not try to solve for x.  Set it up so x is positive.

 

4 HCl(g)   +  O2(g)   <====>   2 Cl2(g)   +  2 H2O(g) Kc = 52
