Answer to Question #142576 in Physical Chemistry for Edet bright

Question

Calculate the potential for the half cell made up of zinc in 0.02M ZnSo4 solution at 298k if the So is 0.763v

Answer 1

Zn²⁺ + 2e^- = Zn

E(Zn²⁺/Zn) = E⁰(Zn²⁺/Zn) + R*T/(2*F)*ln([Zn²⁺]) =

-0.763+8.314*298/(2*96500)*ln(0.02) = -0.813 V

Answer: -0.813 V
