Strongest oxidising agent has the highest tendency to get reduce therefore will have the highest standard reduction potential. So among the given oxidising agents the species have highest value of reduction potential is:
EMnO4−/Mn2+o=1.51V
Given
ECr3+/Cro=−0.74 V; EMnO4−/Mn2+o=1.51V
ECr2O72−/Cr3+o=1.33 V; ECl2∣Cl−o=1.36V
Based on the data given above, strongest oxidising agent will be:

First and second ionization enthalpies of lithium are $520$ kJ mol$^{-1}$ and $7297$ kJ mol$^{-1}$ respectively. Energy required to convert $3.5$ mg lithium (g) into $\text{Li}^{2+}$(g) $[\text{Li(g)} \rightarrow \text{Li}^{2+}\text{(g)}]$ is _______ kJ mol$^{-1}$. (nearest integer) [Molar mass of Li $= 7$ g mol$^{-1}$]
