The electrochemical cell stops working after some time because ________
The reduction potential of hydrogen half-cell will be negative if :(1) PH2= 2 atm and [H+] = 2.0 M(2) PH2= 1 atm and [H+] = 2.0 M(3) PH2= 1 atm and [H+] = 1.0 M(4) PH2= 2 atm and [H+] = 1.0 M
Apply Nernst equation
Therefore E is Negative
