Select the correct answer from the given codes:

• A. A-ii; B-i; C-iv; D-iii
• B. A-i; B-ii; C-iii; D-iv
• C. A-iv; B-iii; C-ii; D-i
• D. A-i; B-ii; C-iv; D-iii

Answer 1

Answer: (A)

A-ii; B-i; C-iv; D-iii

From Gibbs free energy relation we have $\Delta$G= -nF$E$

from first law of thermodynamics we have $\Delta$H= $\Delta$U$+$ P$\Delta$V

from second law of thermodynamics it gives $\Delta$S relation

and for an equilibrium reaction we get $\Delta$$G^0$ = -RT$lo{g}_e$K
