Question
Which of the following redox couple is a stronger oxidizing agent?
\[\ce{MnO^Θ_4}\](E0 = 1.51 V) and \[\ce{Cr2O^{2Θ}_7}\](E0 = 1.33 V)

Solution
\[\ce{MnO^Θ_4}\] has larger positive value of E0 than \[\ce{Cr2O^{2Θ}_7}\]. Thus, \[\ce{MnO^Θ_4}\] is stronger oxidizing agent than \[\ce{Cr2O^{2Θ}_7}\].
