Given,

$straight E subscript Cr to the power of 3 plus end exponent divided by Cr end subscript superscript straight o space equals space minus space 0.74 space straight V semicolon straight E subscript MnO subscript 4 superscript minus divided by Mn to the power of 2 plus end exponent end subscript superscript straight o space equals space 1.51 space straight V straight E subscript Cr subscript 2 straight O subscript 7 superscript 2 minus end superscript divided by Cr to the power of 3 plus end exponent end subscript superscript straight o space equals space 1.33 space straight V semicolon straight E subscript Cl divided by Cl to the power of negative 1 end exponent end subscript superscript straight o space equals space 1.36 space straight V$
Based on the data given above, strongest oxidising agent will be

Cl

Cr³⁺

Mn²⁺

MnO₄^-

Solution

MnO₄^-

Higher the SRP, better is an oxidising agent, among the given $straight E subscript MnO subscript 4 superscript minus divided by Mn to the power of 2 plus end exponent end subscript superscript straight o$ is highest, hence, MnO₄^- is a strongest oxidising agent.
