For the given cell reaction of an electrochemical cell, the change in free energy at a given temperature is a function of Cu 2+ C 1 aq   +   Zn s   → Zn 2+ C 2 aq   +   Cu s

Options

  1. Aln ( C 1 )
  2. Bln ( C 2 )
  3. Cln ( C 1 + C 2 )
  4. Dln ( C 2 / C 1 )

Correct answer

D. ln ( C 2 / C 1 )

Step-by-step solution

E c e l l = E c e l l o - R T n F l n C 2 C 1 and Δ G = - n F E c e l l hence Δ G is the function of l n C 2 C 1
