1)

 All the energy released  from the reaction

   XY,rG0=193kJmol1

  is used for oxidising  M+ as   M+M3++2¯e, E0  =-0.25 V.

 Under standard conditions , the number of moles  of M+ oxidised  when one mole of X is converted to Y  is [F=96500 C mol-]


A) 4

B) 3

C) 2

D) 1

Answer:

Option A

Explanation:

Energy obtained as one mole X is converted into Y is 193 KJ

Energy consumed in converting  one mole of M+ to M3+

      =nE0F=2×96500×0.25J=965002J

   193×103=n(965002)

                 n=4 mol
