Standard electrode potential of three metals X, Y and Z are -1.2 ~V ,+0.5 ~V and -3.0 ~V respectively. The reducing power of these metals will be

Options

  1. AY>X>Z
  2. BZ>X>Y
  3. CX>Y>Z
  4. DY>Z>X

Correct answer

B. Z>X>Y

Step-by-step solution

aligned & E_X^ =-1.2 ~V & E_Y^ =+0.5 ~V & E_Z^ =-3.0 ~V & Z>X>Y[ higher the reduction potential, aligned lesser the reducing power.
