Interpretation:
ΔG0rxn and ΔG0‡ are to be indicated, and ΔG0+is to be compared.
Concept introduction:
In Figure 6-2a and 6-2b, there is an energy maximum along the reaction coordinate. The structure that corresponds to this energy maximum is the elementary step’s transition state. Because there is a maximum in energy between the reactants and products, an energy barrier must be surmounted to form products. This is true regardless of whether the elementary step is exergonic or endergonic. This energy barrier, called the free energy of activation (ΔG0‡, “delta-G-naughtdouble-dagger”), is the difference in standard free energy between the reactants and the transition state. ΔG0‡ is an important factor that governs reaction rates.

([Co(H20)s]*(aq) is pink, [Co(H,0),Cla]? (aq) is purple.) What will happen when large amounts of Ag(NO;) (aq) are added to the reaction and why? (Please use the solubility table in your lab manual.) a) Reaction color will change to pink because cobalt and nitrate will form a precipitate and cobalt will be taken out of solution. b) Reaction color will change to pink because silver and chloride will form a precipitate and chloride will be taken out of solution. c) Reaction color will change to purple because silver nitrate will absorb water and it will be taken out of solution. d) Reaction color will change to purple because we are adding a reactant.arrow_forward
