Answer:
The value is 
Explanation:
From the question we are told that
The voltage of the cell is 
Generally 
is mathematically represented as
Where 
is the equilibrium constant for this auto-ionization of water with a value 
Generally the 
is mathematically represented as
=> 
=> 
This is mathematically represented as
Where n is the number of moles which in this question is n = 1
So
=> 
So
=> 
=>
Answer:
The overall cell potential must be positive.
Explanation:
What must be true for a spontaneous reaction in an electrochemical cell?
- The overall cell potential must be positive. YES. This is by convention.
- The overall cell potential must be negative. NO. By convention, a negative cell potential means the cell is not spontaneous.
- The cathode’s standard reduction potential must be positive. NO. It only has to be higher than the anode's standard reduction potential.
- The cathode’s standard reduction potential must be negative. NO. It only has to be higher than the anode's standard reduction potential.
