Unformatted text preview: first prepared, the predominant species was [Co(H 2 O) 6 ] 2+ . When the tube was heated to 100°C, the predominant species became CoCl 4 . Juan Robledo CH118-L9 Chemical Equilibrium and LeChatelier’s Principle After the tube was removed from the heat and placed into an ice bath, the predominant species moved back to [Co(H 2 O) 6 ] 2+ . 4. Exercise When a reaction leaves the standard state because of a change in the ratio of the concentrations of the products to the reactants, we have to describe the system in terms of non-standard-state free energies of reaction. The difference between G o and G for a reaction is important. There is only one value of G o for a reaction at a given temperature, but there are an infinite number of possible values of G ....
