Question

Part A

The standard reduction potentials of lithium metal and chlorine gas are as follows:

Reaction Reduction potential (V) Li+(aq)+eLi(s) 3.04

Cl2(g)+2e2Cl(aq) +1.36 In a galvanic cell, the two half-reactions combine to 2Li(s)+Cl2(g)2Li+(aq)+2Cl(aq) Calculate the cell potential of this reaction under standard reaction conditions.

Part B

Calculate the free energy G of the reaction.

Part C

What can be said about the spontaneity of this reaction?

spontaneous as written. spontaneous in the reverse direction. at equilibrium. nonspontaneous in either direction.

Explanation / Answer

part A)

Eo = 3.04 + 1.36 = 4.40 V

part B)

dGo = -nFEo

dGo = -2*96485*4.40

dGo = - 849.068 kJ

part C)

since dG is negative reaction is spontaneous
