CH E485 Lecture 10: 10- Electrode Reactions and EMF Series

The magnitudes of the standard electrode potential of two metals, X and Y, are X^1+ + 1e = X |E degree| = 0.15 V Y^2+ + 2e = X |E degree| = 0.44 V where |E degree| denotes the absolute value in magnitude but not the sign of E degree. When the half-cells of X and Y connected, electrons flow from X to Y. When X is connected to a standard hydrogen electrode (SHE), electrons flow from X to SHE. (a) What are the signs of the standard electrode potential for the above two half-cell reactions? (b) What is the standard emf of a cell made of X and Y?

The magnitudes of the standard electrode potential of two metals, X and Y, are X^1 + le^= X |E degree| = 0.15 V Y^2+ 2e^= Y |E degree| = 0.44 V where |E degree| denotes the absolute value in magnitude but not the sign of E degree. When the half-cells of X and Y connected, electrons flow- from X to Y. When X is connected to a standard hydrogen electrode (SHE), electrons flow- from X to SHE. (a) What are the signs of the standard electrode potential for the above two half-cell reactions? (b) What is the standard emf of a cell made of X and Y?
