Given:
 
Cell:
 
Pt | H2 (P1) || H+ (g, P2 ) || Pt
 
RHS:
 
RHS
2 straight H to the power of plus space plus space 2 straight e to the power of minus space rightwards harpoon over leftwards harpoon space space straight H subscript 2 left parenthesis straight P subscript 2 right parenthesis

LHS

straight H subscript 2 left parenthesis straight P subscript 1 right parenthesis space rightwards harpoon over leftwards harpoon space 2 straight H to the power of plus space plus space 2 straight e to the power of minus

Overall space reaction space is comma

straight H subscript 2 left parenthesis straight P subscript 1 right parenthesis space rightwards harpoon over leftwards harpoon space straight H subscript 2 left parenthesis straight P subscript 2 right parenthesis
 
Nernst Equation,
 
straight E space equals space straight E to the power of ring operator minus RT over nF ln straight P subscript 2 over straight P subscript 1

space space space space equals 0 space minus RT over nF ln straight P subscript 2 over straight P subscript 1


straight E space equals RT over nF ln straight P subscript 1 over straight P subscript 2
