An aqueous solution is made by mixing 4.3 mL of 0.40 M Co(NO3)2 and 8.7 mL of 12.0 M HCI, and the following is the equilibrium reaction that takes place. [Co(H2O)6]2*(aq) + 4CI" (aq) <-----> [COCI42 (aq) + 6H20() Assuming the above reaction is exothermic in the forward direction (toward the product side), predict whether the following statements (in relation to the above equilibrium reaction in aqueous solution) are "True" or "False". True False In the ddition of HCI, equilibrium will not be shifted to either side because H* ions (from HCI) react with NO3 (from cobalt (II) nitrate) and form HNO3. True False The above equilibrium reaction has a negative enthalpy change in the reverse direction (toward the reactant side). True False Addition of HCl does not affect the position of equilibrium as HCI does not appear in the equilibrium reaction equation. True False Cooling causes the equilibrium to shift to the right (product side). True False In the addition of H20, the reaction mixture will be diluted but equilibrium will not be shifted to either side.
