Question

The following facts are available 2X- + Y2 → 2Y-+ X2 2W- + Y2 → No reaction 2Z-+ X2 → 2X- + Z2 Which of the following statements is correct? (A) EoW-/W2 > EoY-/Y2 >Eo X- /X2 >Eo Z-/Z2 (B) EoW-/W2 < EoY-/Y2 < Eo X- /X2 < Eo Z-/Z2 (C) EoW-/W2 < EoY-/Y2 >Eo X- /X2 >Eo Z-/Z2 (D) EoW-/W2 > EoY-/Y2 < Eo X- /X2 < Eo Z-/Z2

2X- +Y2 →2Y- +X2 → Eo Y2/Y- >Eo X2/X- 2Z- +X2 →2X- +Z2 → Eo X2/X- >Eo Z2/Z- 2W- +Y2 → no reaction ⇒ Eo W2/W- >EoY2 /Y-

Q. The following facts are available
$2 X^{-} + Y_{2} \to 2 Y^{-} + X_{2}$
$2 W^{-} + Y_{2} \to$ No reaction
$2 Z^{-} + X_{2} \to 2 X^{-} + Z_{2}$
Which of the following statements is correct?

$E_{W^{-} / W_{2}}^{o} > E_{Y^{-} / Y_{2}}^{o} > E_{X^{-} / X_{2}}^{o} > E_{Z^{-} / Z_{2}}^{o}$

$E_{W^{-} / W_{2}}^{o} < E_{Y^{-} / Y_{2}}^{o} < E_{X^{-} / X_{2}}^{o} < E_{Z^{-} / Z_{2}}^{o}$

$E_{W^{-} / W_{2}}^{o} < E_{Y^{-} / Y_{2}}^{o} > E_{X^{-} / X_{2}}^{o} > E_{Z^{-} / Z_{2}}^{o}$

$E_{W^{-} / W_{2}}^{o} > E_{Y^{-} / Y_{2}}^{o} < E_{X^{-} / X_{2}}^{o} < E_{Z^{-} / Z_{2}}^{o}$

$2 X^{-} + Y_{2} \to 2 Y^{-} + X_{2} \to E_{Y_{2} / Y^{-}}^{o} > E_{X_{2} / X^{-}}^{o}$
$2 Z^{-} + X_{2} \to 2 X^{-} + Z_{2} \to E_{X_{2} / X^{-}}^{o} > E_{Z_{2} / Z^{-}}^{o}$
$2 W^{-} + Y_{2} \to n o re a c t i o n \Rightarrow E_{W_{2} / W^{-}}^{o} > E_{Y_{2} / Y^{-}}^{o}$
