Consider the following reaction: I2(g) + Cl₂ (g) = 2IC1(g) Kp = 81.9 at 25° C. Calculate AGrxn for the reaction at 25° C under each of the following conditions.

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. 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. O 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. The reaction is very product-favoured, and the chloride concentration will be much smaller than the cyanide concentration.
