Question
A galvanic cell is constructed using the two hypothetical half-reactions
A + e– → B E° = +1.50 V 
C + 2e– → D E° = –0.50 V

 

Determine the balanced chemical equation.

Calculate the total overall voltage.

 

Question 7 options:

 

a) 

2 A  +  C  -->  2 B  +  D

E°total =  +1.00 V
 

b) 

A  +  C  -->  B  +  D         

E°total = +1.00 V
 

c) 

A  +  D  -->  B  +  C

E°total =  +2.00 V
 

d) 

B  +  C  -->  A  +  D

E°total =  -2.00 V
 

e) 

2 B  +  C  -->  2 A  +  D

E°total =  -2.00 V
 

f) 

2 A  +  D  -->  2 B  +  C

E°total =  +2.00 V
