Given that$\mathrm{E}°$values of${\mathrm{A}\mathrm{g}}^{+}/\mathrm{A}\mathrm{g},\mathrm{ }{\mathrm{K}}^{+}/\mathrm{ }\mathrm{K},\mathrm{ }{\mathrm{M}\mathrm{g}}^{2+}/\mathrm{M}\mathrm{g}\mathrm{ }\mathrm{ }$and${\mathrm{C}\mathrm{r}}^{3+}/\mathrm{C}\mathrm{r}\mathrm{ }$are$0.80\mathrm{V},\mathrm{ }–2.93\mathrm{V},–2.37\mathrm{V}\mathrm{ }$and$–0.74\mathrm{V}$respectively. Therefore the order for the reducing power of the metal is -
