Question

Consider the following equations for a cell reaction

Answer 1

Answer: I think should be the solution

Explanation:

Answer 2

The following equations for a cell reaction, x=y, K1=K2

Explanation:

• The given reaction are:
• A+B⇌C+D  ;E°  =xv°

         Keq  = K1 =    [C][D]/ [A][B]     →(I)

         2A+2B ⇌ 2C+2D    ;E°  =yv

         ​K eq = K2 =  [C]²  [D]²   /[A]² [B]²  

          K  2  = K1²

• Now, EMF of the cell having a particular reaction does not change on multiplying or dividing the balanced chemical reaction with a constant.
• So,  x=y,   K1 ²  =K 2 .
