Which one of the following statements best describes the following equilibrium at 298 K: CUCN(s) + CI (aq) = CuCl(s) + CN (aq) K = 2.0x10-13 at 298 K O The reaction is very reactant-favoured, and the cyanide concentration will be much smaller than the chloride concentration. O The reaction will proceed to the left until either CuCl or cyanide is fully consumed. O The reaction will proceed to the right until either CUCN or chloride is fully consumed. The direction and extent of reaction cannot be determined conclusively without knowing the sign and magnitude of the enthalpy change for the reaction, A-H. O The reaction is very product-favoured, and the chloride concentration will be much smaller than the cyanide concentration.
