a. Cl₂(E⁰ = 1.36 V) and Br₂ (E⁰ = 1.09 V)

Cl₂ has a larger positive value of E⁰ than Br₂.

Thus,

Cl₂is a stronger oxidizing agent than Br₂.

b. MnO₄^Θ(E⁰ = 1.51 V) and Cr₂O₇^2Θ (E⁰ = 1.33 V)

MnO₄^Θ has larger positive value of E⁰ than Cr₂O₇^2Θ.

Thus,

MnO₄^Θis stronger oxidizing agent than Cr₂O₇^2Θ.
