The standard potential of the given cell reaction and the standard Gibbs energy and enthalpy values have to calculated at 25 o C . Concept Introduction: In any electrochemical reaction, an electron goes from one substance to another substance driven by the oxidation-reduction reaction. Electrochemical cells have two conducting electrodes, called the anode and cathode. The anode is defined as the electrode where oxidation occurs. The cathode is the electrode where reduction takes place. Standard electrode potential ( E ° c e l l ) can be calculated for both oxidation and reduction reactions. A positive value of ( E ° c e l l ) indicates that the reaction proceeds spontaneously in the forward direction whereas, a negative value of ( E ° c e l l ) indicates that the reaction proceeds spontaneously in backward direction. The standard cell potential expression is written as follows, E ° c e l l = E ° c a t h o d e − E ° a n o d e

Question

Chapter 5, Problem 5.67P

(a)

Interpretation Introduction

Interpretation:

The standard potential of the given cell reaction and the standard Gibbs energy and enthalpy values have to calculated at 25oC.

Concept Introduction:

In any electrochemical reaction, an electron goes from one substance to another substance driven by the oxidation-reduction reaction. Electrochemical cells have two conducting electrodes, called the anode and cathode. The anode is defined as the electrode where oxidation occurs. The cathode is the electrode where reduction takes place. Standard electrode potential (E° cell) can be calculated for both oxidation and reduction reactions. A positive value of (E° cell) indicates that the reaction proceeds spontaneously in the forward direction whereas, a negative value of (E° cell) indicates that the reaction proceeds spontaneously in backward direction. The standard cell potential expression is written as follows,

E° cell = E° cathode − E° anode
