question 100

Multiple Choice

The standard cell potential for the nickel-cadmium battery is 1.35 V, and the cell reaction can be written as Which one of the following statements do you expect to be true based on the Nernst equation? Note Q  reaction quotient, and K  equilibrium constant for the cell reaction.

• A)As the battery is used, the cell voltage approaches zero because Q approaches K in value.
• B)When the battery no longer works, the cell voltage is zero because Q  K.
• C)As the battery is used, the cell voltage does not change because Q equals 1.
• D)When the battery is fully charged, Q  K.
• E)When the battery is fully charged, Q  K.
