A voltaic cell is assembled under standard conditions based on the following reaction :
Ni(s) + 2 Ag+(aq) → Ni+2(aq) + 2 Ag(s)
Indicate which statements, if any, about this voltaic cell are true by checking the box in front of each true statment. -
The voltaic cell will always produce a positive potential. If the [Ni2+] is doubled while [Ag+] remains standard, the intial potential produced by the voltaic cell will double.
If the [Ag+] is doubled while [Ni+2] remains standard, the intial potential produced by the voltaic cell will double.
If [Ni2+] less than 1.0 M is used while [Ag+] remains standard , the initial potential will be greater than the standard potential for the voltaic cell.
If [Ag+] less than 1.0 M is used while [Ni+2] remains standard , the initial potential will be greater than the standard potential for the voltaic cell.
The potential produced by the voltaic cell may be affected by temperature.
The value of K for the voltaic cell reaction is greater than 1.
The value of K for the voltaic cell reaction is less than 1.
