D G o is zero and K is greater than 1. D G o is positive and K is greater than 1. D G o is positive and K is less than 1. 6. If a certain reaction has a negative value for D H and a positive value for D S, the reaction a. will be spontaneous at all temperatures. Br2 is the reduced at the cathode.
Electrons travel from the cathode to the anode through an external wire.
Br2 is the oxidizing agent.
