Both the forward and reverse reactions of the following equilibrium are believed to be elementary steps:
CO(g) + Cl2(g) COCl(g) + Cl(g)
At 25.0°C the rate constants for the forward and reverse reactions are 1.40 x 10-28 M-1 s-1 and 9.30 x 1010 M-1 s-1, respectively. What is the value for the equilibrium constant at 25.0°C?
