Question
Consider this reaction at equilibrium: Cd2+(aq) + 6CN-(aq) Cd(CN)62-(aq) Colorless colorless (a) If the concentrations of CN-(aq) isincreaced, how do you expect the concentrations of the otherspecies to change? Explain reasoning. (b) Why would you not use the same approach in determining howtempeature affects equilibrium here than in two cobalt(II)complexes.

Explanation / Answer
(a) If you increase CN, then Cd2+ will decrease andCd(CN)62- will increase, because since thereare now more reactants, the reaction will go in the forwarddirection. (b) If you increase heat, the reaction will go in the forwarddirection.
