the equilibrium concentrations for the reaction between carbon monoxide and molecular chlorine to form cocl2 (g) at 74 degrees celsius are [co]= 0.012M and [cl2] = 0.054 M. if Kc = 210 at this temperature. calculate the equilibrium concentration of COCl2?

The reaction between CO and Cl2 takes place as follows:
CO + Cl2 > < COCl2
Kc = [COCl2]/[CO][Cl2}
Here Kc = 210
At equilibrium
[CO] = 0.012M; [Cl2] = 0.054M; [COCl2] = ?
Substituting the given values in the above equation, we get
210 = [COCl2]/(0.012 x 0.054)
Thus [COCl2] = 210 x 0.012 x 0.054 = 0.136M
