Cd 2+ + 2 e - Cd (s) E 1/2 o = -0.40 V VO 2 + + 2H + + e - VO 2+ + H 2 O E 1/2 o = 1.00 V 3.If the concentration of Cd 2+ is reduced from 1.0 M to 0.01 M in the Cd half cell, and all other concentrations remain at their standard values, what happens to the potential of the cell? A.The cell potential increases B.The cell potential decreases C.The cell potential remains the same D.The cell potential becomes zero E.None of the above

Chemical Kinetics Some examples of questions kinetics tries to answer •When reactants are brought together, how fast do they react (rates of reaction)? •What influences the rate at which they react? •What is the detailed sequence of changes that occur during a reaction (mechanism). •How is the mechanism for a reaction related to the
