IF CHANGE IN GIBBS ENERGY FOR A REACTION ISO (A+) + (B-) =(A2+) + (B2-) IS x, THEN FIND IT FOR RXN-
(0.5A+) + (0.5B-) = (0.5A2)+ + (0.5B2-)

Expert Answer
For ELECTROCHEMICAL cell:
(A+) + (B-) =(A2+) + (B2-)
ΔG=nFEo
and in first reaction n=1
and hence, x=1*FEo
and for (0.5A+) + (0.5B-) = (0.5A2)+ + (0.5B2-)
here
n=.5
hence,ΔG=.5FEo
which can be written as,ΔG=.5FEo =x/2
