Both the forward reaction and the reverse reaction in the following quilibrium are believed to be elementary steps:
CO(g) + Cl2(g) ↔ COCl(g) +Cl(g)
At 25 °C the rate constants for the forward and reverse reactions are and 1.4 X 10-28 M-1 s-1 and 9.3 X 1010 M-1 s-1, respectively.
(a)What is the value for the equilibrium constant at 25 °C?
(b) Are reactants or products more plentiful at equilibrium?
(c) What additional information would you need in order to decide whether the reaction as written is endothermic or exothermic?
